It is now a more or less permanent annual fixture on the chart calendar. This, the week immediately following the Glastonbury Festival when we note the effect the wall to wall coverage of the big headline performances has had on the music sales of the artists in question. What was once a small folk festival on a piece of farmland has now become a pivotal moment in an artist's career, and with the digital era enabling enthusiastic purchase of their catalogue (often whilst they are singing the very song on stage), it just wouldn't be Glastonbury without at least one act experiencing that most satisfying of chart rushes.
Step forward then Beyonce, climactic performer on the pyramid stage and this week the undisputed chart queen no matter which way you try to spin things.
Now in fairness even without Glastonbury, the release of her brand new solo album 4 was always going to be a significant chart event, but its oh so neatly timed release has inevitably sent it soaring to the Number One position, in the process becoming her first chart-topping release since Dangerously In Love debuted at the top exactly eight years and one week ago. Indeed her catalogue has taken a suitable pounding following her televised performance last weekend, with the aforementioned debut album marching back up the chart to Number 45, just a few places behind I Am… Sasha Fierce which sits at Number 38.
It will not have escaped your attention that 4 is by no means the first Number One album this year to be titled with a number rather than an actual name, and indeed with 21 sitting at Number 2 and 19 at Number 5, the chart is uniquely dominated by numerically titled offerings. Believe it or not it wasn't until Status Quo's 1982 that anyone topped the chart with an album named after a number, but since the 1990s we have been on something of a roll: 1977 by Ash; 13 by Blur'; 7 by S Club 7; 1 by The Beatles; 8701 by Usher; 18 by Moby'; and most recently 19 and 21 by Adele.
Beyonce was at one stage set to do a post-Glastonbury chart double with the second single from 4 entitled Best Thing I Never Had moving full steam ahead for Number One. In the end its sales turned out to be rather front loaded and by the weekend it had flagged, landing instead at Number 3 and at the very least beating the slightly disappointing Number 11 peak of her last hit Run The World (Girls) and in the process becoming her biggest hit single as lead artist since If I Were A Boy topped the charts in late 2008 - although she has made Number One since as co-singer on Lady Gaga's Telephone which topped the charts in 2010.
With Beyonce out of the way, Jason Derulo spends a second week at Number One with Don't Wanna Go Home, whilst the track he deposed Changed The Way You Kiss Me by Example clings on at Number 2.
Needless to say other items from Beyonce's catalogue have benefited nicely from a Glastonbury surge, with Run The World (Girls) climbing back up to Number 23 in its highest chart placing for five weeks. Her third Top 40 single of the week is 2006 Number 4 hit Irreplaceable which charges back onto the chart at Number 33 in what appears at first to be a rather random manner. Its newfound popularity is actually due to it being one of three live tracks from the festival which have been released as 30 day limited editions in aid of the festival's nominated charities. Most sales of Irreplaceable during the week have been for this live version, but under chart rules it is combined with the sales and inherits the chart history of the studio original, hence counting as a re-entry rather than a brand new hit.
The Glastonbury effect isn't confined to Beyonce though, as fellow headliners Coldplay see their chart fortunes take a turn for the better after they reprised their 2000 appearance which put them on the map for the very first time. With their new album still unreleased, their back catalogue receives a minor chart tickle but it is current single Every Teardrop Is A Waterfall which makes the most dramatic move. After debuting at Number 6 a fortnight ago the track had echoed its title and embarked on rapid trip downwards, plummeting to Number 42 last week. One live performance later and the single makes one of the most dramatic one week yo-yo's I can ever remember, surging 32 places back up the chart to sit pretty at Number 10. Only a handful of singles have ever made the Top 10 twice in the same chart run after dropping out of the Top 40 altogether, most memorably Ghostbusters by Ray Parker Jnr in 1984, but I think Coldplay's feat of rebounding back to the upper reaches from outside the Top 40 in a single week is pretty much unique.
Coldplay's exclusive live charity release was their performance of In My Place and so inevitably that is their second biggest selling single of the week, the track arriving at Number 40 in its first chart appearance since it made Number 2 way back in August 2002. 2005 single Fix You is at Number 47 with former Number One Viva La Vida at Number 51 , Yellow at Number 59 and The Scientist at Number 68.
The third live exclusive single was I Will Follow by U2 but bizarrely, despite the positive reaction to their own headlining set, the single can only make Number 78 and indeed is the only U2 track in the Top 100. On the album chart, their only chart move of note is the 107-61 leap of U218 Singles. Maybe everyone who wants them already owns all the U2 music they can manage, but of all three headlining acts it is the Irish legends who appear to have benefited the least from the Glastonbury effect.
You have to look carefully, but there is other chart action taking place away from the festival season. Making a two place climb to Number 9 on the singles chart is Last Friday Night (TGIF) from Katy Perry who thus bags herself five Top 10 singles from the Teenage Dream album. Whilst the track itself is as much a piece of lightweight fluff as many of its immediate predecessors, it is at the very least redeemed by the hugely entertaining video which features cameo appearances from a number of famous names ranging from Hanson to Kenny G and Debbie Gibson, but the show surely has to be stolen by the wonderfully knowing appearance of Rebecca Black who naturally is the expert on all matters Friday related.
Adele's Set Fire To The Rain continues its slow burn up the listings, moving two places to Number 21 in its highest chart position to date. Although the record books will note that it is for the moment a rather disappointing follow-up to the Number One triumph of Someone Like You this must still be tempered with the fact that parent album 21 this week spends its sixth straight week at Number 2 and its 23rd in a row in the Top 2 of the sales chart. Frankly the biggest selling album of the year by a distance hardly needs a third hit single to boost its sales further.
Finally watch out in the coming weeks for Dirty Dancer from Enrique Iglesias and Usher which enters the Top 40 at Number 28. It is the follow-up to the rather gloriously rude Tonight (I'm <expletive> You) which peaked at Number 5 back in February.
