Proof that you cannot keep a good album down, Pink Floyd's 1973 classic "The Dark Side Of the Moon" has earnt its highest rank on the Billboard 200 chart since 1980 as it has re-entered at No. 69, helped, no doubt, with Amazon.com offering the MP3 download of the album as a "deal of the day" at $1.99!

In other DSOTM news, BBC4 TV in the UK is airing a multipart scientific series named "The Beauty of Diagrams". On December 2nd the series looked at "Newton's Prism". In the programme, they compared Dark Side's iconic cover with Newton's Prism. As part of this, they undertook a short but interesting interview with Storm Thorgerson on the album cover.

The show will be repeated in due course, but you can see it now via the BBC iPlayer. Storm's interview starts at about 20 minutes and 50 seconds into the show, and goes on to around the 23 minutes, 30 seconds point.

Our thanks to Dr Najam Beg, and to David Haddock, for the Newton programme info.

Further to our story a couple of weeks ago concerning the Pink Floyd quadrophonic consoles which are being offered for auction at Bonhams in London's Knightsbridge on December 15th, there's a couple of other items of great interest to Floyd fans in the sale.

First, there's lot 155: a poster for a long-forgotten concert that Pink Floyd performed at Dunelm House, at the University of Durham, on March 20th, 1969. Until this poster appeared in the catalogue, this show had not been noted anywhere and was destined to be just a memory for a lucky few. The estimated selling price for this is £450-550.

The other item is lot 284: a one-off Epiphone Casino guitar signed by a host of rock legends with the proceeds going to Pup Aid. The charity was launched by Oasis singer Liam Gallagher to raise awareness of the terrible trade of puppy farming. The guitar is expected to sell for between £3000-4000, and is signed by the likes of Jimmy Page, Keith Richards, Eric Clapton, Brian May, Roger Daltrey, and David Gilmour, amongst others.

More details of the auction can be found at www.bonhams.com/entertainment.

It is typical that as we make comments that "the [Paris] show concludes the European tour", it's obvious that additional announcements are going to be made! True to form, yet another show has this evening been confirmed in Europe, right at the end of the schedule.

Making a grand total of five shows at the venue (albeit split by a few months!), Roger will be taking the production back to the Mediolanum Forum di Assago, in Milan, Italy, on July 6th 2011. Tickets will be available through www.Ticketone.it and other normal agents.

TICKETING FOR PARIS and MILAN: An update on the RogerWaters.com presales for the two shows announced today - the RW presales started TODAY, and you should take a look at your mailbox for an email if you've registered an interest in either city.

Another addition to the European leg of the Roger Waters - The Wall Live tour today. With the first two shows selling out in a couple of hours, a third night has been lined up at the Palais Omnisports de Paris Bercy, in the French capital, on June 30th.

This date, at time of writing this anyway, concludes the European tour and is the final confirmed concert of the whole enterprise. With the recent additions though, we're not sure this situation will last too long!

General sale tickets will be available from December 10th, 2010, through FNACspectacles.com.
