In the early days of Pink Floyd, the Roundhouse in London was a regular venue for the band. Some of the performances were quite notable, with one show in particular including their van being driven (accidentally) backwards into a huge pile of jelly (moulded in a bath tub) in the middle of the venue, when they arrived to drop off their equipment.

Early Pink Floyd concert posters hold a special place in the hearts of many fans, but originals are extremely hard to track down - and are eye-wateringly expensive. However, tapping in to this market the Roundhouse have put on sale reproductions of some of their classic posters, including two different Pink Floyd examples.

Both posters are for the same show, the Roundhouse's first gig, the 1966 All Night Rave on October 15th, 1966. The show was a lavish event to launch the International Times newspaper. The first of the prints on offer is the hand written concert bill for the show, and the second is the far more professional looking, more traditional poster which urged attendees to "Bring your own poison"!

The posters are available in a range of sizes, and also as canvasses, mini prints, and acrylic prisms.

You can place your orders now through prints.roundhouse.org.uk, who ship to a wide variety of countries worldwide.

Back in October 2005, BBC's Mastermind included Pink Floyd as one of the contestants' chosen subjects.

For those of you unfamiliar with this show, in a nutshell, four contestants take it in turns to answer questions over two rounds, against the clock. The first two-minute round comprises questions on each contestant's chosen specialist subject, and the second two-minute round tests general knowledge. The winner of each contest goes forward to the next knockout phase of the competition. It is one of the most popular quiz programmes on television, having run for forty-two years.

For the second time in the programme's history, someone has chosen to answer questions about Pink Floyd - and this week's show, which airs on the UK's BBC Two this coming Friday night, November 21st, at 8pm. More details can be found at the BBC website. Our thanks to David Haddock and Matthew Setchfield for letting us know about this.

As before, we will make a note of the questions (and the given answers) so you can all give the quiz a try - especially those who don't want the pressure of answering the questions 'live' in front of their families!

This evening, Pink Floyd's new album, The Endless River, went straight in to the UK's official album charts at the coveted number one spot, demoting Ed Sheeran's album X, and keeping the new Calvin Harris album Motion at bay. Taylor Swift's album 1989 also felt the Floyd effect. The new Queen and Foo Fighters albums couldn't compete either. It is Pink Floyd's sixth UK number one, and the last time the group topped the chart was back in 1995 with live double album, PULSE.

A spokesperson for the band told OfficialCharts.com: "Pink Floyd is both thrilled and surprised at the level of international interest in this their final album. They want to thank the fans for their support and hope that in some small way, The Endless River has reminded them of the old fashioned joy of listening to an album in its entirety."

Album charts in other countries are now also starting to show The Endless River, and it has reached number one in Belgium, Croatia, Germany, Ireland, Israel, the Netherlands, New Zealand and Norway. Italy and Australia are clearly tougher nuts to crack, with the album entering their charts at number two and three respectively.

On the subject of The Endless River, our exclusive interview with Egyptian cover artist Ahmed Emad Eldin will be here very shortly, giving you some background to Ahmed, his life and work, and what TER's cover image was originally called...

UPDATE: Pink Floyd's official Facebook page has been updated to reveal that the album is now number one in twenty countries - UK, Germany, France, Canada, The Netherlands, Belgium, Portugal, Hungary, Austria, Switzerland, Denmark, Norway, Ireland, New Zealand, Poland, Sweden, the Czech Republic, Italy, Croatia and Slovenia. Other charts include: USA � 3, Australia � 3, Finland � 4, Spain � 6, with many more to come. They also note that TER is the best-selling album in Romania, although there are no official charts there.

The well-respected UK radio station Planet Rock are broadcasting a new episode of their one-hour show, My Planet Rocks, now in its tenth series, tonight at 7pm UK time.

In this week's My Planet Rocks, David Gilmour talks to PR presenter Darren Redick about Pink Floyd's new album The Endless River, which they also promise to play "large chunks of the record itself". The interview was conducted on board Astoria, David's floating houseboat recording studio, as you'll note from the picture to the right. You can hear the interview tonight (Sunday, November 16th) at 7pm, and again on Thursday, November 20th, at 8pm.

Those in the UK can tune in on DAB radio, via Sky satellite TV (channel 0110), Virgin Media digital cable (channel 924), or Freesat (channel 730). Alternatively, fans worldwide can listen in via their website: PlanetRock.com. They also have a "Listen Again" facility online but we cannot guarantee that this new show will be available through that route - although it should be there soon.
