Our very best wishes, and many happy returns, to David Gilmour today, who is no doubt celebrating his 67th birthday!

Born and raised in Cambridge, David became involved with various bands in the area, principally Jokers Wild who were a popular draw when they played, before joining Pink Floyd in 1968. More recent years have seen David concentrating on his solo career, and helping out chums on their musical projects on an ad hoc basis - such as appearing on stage with Phil Manzanera at the legendary Ronnie Scott's Jazz Club, with Amadou & Mariam at the Crisis "hidden" charity show, with Jeff Beck at the Royal Albert Hall, and most recently - just after his birthday last year - the Douglas Adams 60th Birthday concert at London's Hammersmith Apollo.

With it being now an incredible seven years to the day (how time flies!) since the release of his last solo album, On An Island, many people's thoughts are on whether we might see a follow up to that. We can only hope that rumours of him working on new music, encouraged by Polly talking about helping out with lyrics, bear fruit at some point. In the meantime, of course, we wish David a very happy day!

The 2013 Record Store Day takes place on April 20th, and includes within its many limited edition exclusives a very special Pink Floyd single - and we have full details for you.

Record Store Day now occurs each year, takes place across many countries, and celebrates the work of small, independent shops with a range of one-day-only special releases, unavailable elsewhere and while stocks last. In 2011, a limited "Pink Floyd The Wall: Singles Box" flew off the shelves on RSD, and this latest release is bound to be as popular.

It's a limited (but not numbered), one-off 7" pink vinyl pressing of 'See Emily Play/The Scarecrow'. It comes in an EMI house single bag, together with a card insert featuring Syd Barrett's artwork, and then the whole thing is shrinkwrapped.

The quantities are limited within the territories that have ordered it, which include: Australia, Austria, Belgium, Canada, Finland, France, Germany, Greece, Italy, Japan, Malaysia, Netherlands, NZ, Norway, Poland, Portugal, Russia, Slovenia, Spain, Switzerland, Sweden, UK, and the USA.

Full details of other releases, and participating stores, not just in North America, but worldwide, can be found at RecordStoreDay.com. Should online retailers feature it too, we will let you know as and when information comes our way.

Pink Floyd's groundbreaking concept album "Dark Side of the Moon" is a staggering 40 years old this month. As the BBC note, you could say its themes are just as relevant today - madness, money, identity, disorientation, all the stresses of the modern world. But in 1973, its construction was startling - with its musical episodes flowing one into the other, and its looped and layered sound effects. It's credited as one of the most influential rock albums of all time. Yesterday afternoon BBC World sat down with Nick Mason in his North London loft, and asked him whether they'd ever suspected the album would be so big...

You can hear the interview on demand through the following:

Just announced this morning is an additional date for the 2013 Roger Waters The Wall Live tour - the massive production will be performed at the Manchester Arena in England on Monday 16th September 2013. Tickets go on sale on Friday, March 1st at 9am UK time, through this direct link to Ticketmaster UK, along with other official agents. The venue is not a stranger to Roger - it was the site of three Wall concerts in 2011. Since those concerts, the naming rights have expired, and whilst then it was known as the Manchester Evening News (MEN) Arena, the newspaper's title has now been dropped for the simpler name of Manchester Arena.

The Brain Damage showpage for this concert has now been set up and as with all the other dates on the 2013 tour, we welcome any ticket scans, posters, photos, thoughts on the show, and more.
