Yesterday, David Gilmour and Polly Samson appeared at the Hay on Wye Literature Festival to discuss their songwriting partnership, and the writing process between lyricist and musician.

For those who missed the event, the BBC website has today posted the entire session to view. Restrictions may apply in certain countries, but hopefully most of you at least will be able to watch the following:

The UK's Royal Mail today reveal images of a set of 10 stamps that will be issued to mark the time since Pink Floyd turned professional (at the start of 1967) and became the 'house band' of the London Underground movement of music and arts. The stamps are available to pre-order from today, May 26th at www.royalmail.com/pinkfloyd and to purchase from 8,000 Post Offices across the UK from July 7th, the official "on sale" date.

Six stamps feature iconic album covers: The Piper at the Gates of Dawn; Atom Heart Mother; The Dark Side of the Moon; Wish You Were Here; Animals and The Endless River. In 2014, The Division Bell was issued by the Royal Mail in a similar edition, but in the midst of a range of covers by different artists.

A further four stamps within a miniature sheet celebrate the live performances of the band. Arguably the most visually literate band of all time, as well as being one of the most successful, their live appearances were renowned. They were among the first groups to make extensive use of light shows and projection of films for their appearances, increasing in ambition over the decades.

The four images convey the experience of these live performances, from the appearances at the influential UFO Club, London in 1966 where they stunned audiences with their revolutionary, psychedelic light show; to the extremely ambitious staging for albums such as The Wall and the Division Bell tours.

The Royal Mail website are offering a variety of different editions, and special presentation items, such as First Day Covers, framed prints, and more - all destined to be very collectable items. Place your orders now through www.royalmail.com/pinkfloyd.

With David Gilmour's 2016 Rattle That Lock tour resuming in just over a month's time, his official Facebook page has issued an update, a brief look at the first show on the upcoming schedule, and reveals that there has been some slight personnel changes for the band.

The last leg of the tour kicks off in Wroclaw, Poland, with a show at Plac Wolnosci (Freedom Square) in front of television cameras, directed by Aubrey 'Po' Powell for a live broadcast on the country's TV. As previously confirmed, the show will include a 30-piece orchestra conducted by long term Gilmour collaborator Zbigniew Preisner.

For the final bunch of shows, the band will include some interesting new members. Here's how they line up alongside David: on bass, Guy Pratt; drums, Steve DiStanislao; Chester Kamen on guitar; on keyboards there's Greg Phillinganes and Chuck Leavell; Brazilian Joao Mello returns on saxophone; and there's Louise Marshall, Lucita Jules and Bryan Chambers all on vocals.

Chester Kamen will be a very familiar name to many of you; he was guitarist for Bryan Ferry in 1985, when David joined Bryan, Chester and Jon Carin on stage at Wembley Stadium for the Live Aid concert - Chester and David also play guitar on Bryan's 1985 album Boys And Girls, and 1987's follow-up, Bete Noire. Chester also played on Roger Waters' 2002 In The Flesh tour.

Chuck Leavell was a former member of the Allman Brothers, and performed with David at the Capitol Theater in Passaic, New Jersey in 1984. Greg Phillinganes has a long CV, and in particular worked extensively with Stevie Wonder, The Jacksons/Michael Jackson, and Eric Clapton.

The annual Teenage Cancer Trust concerts at the Royal Albert Hall in London normally involve creating some special merchandise for each of the shows during the week of events, all raising much needed funds for this wonderful charity.

As you know, this year's closing concert was performed by David Gilmour, and the show was praised for its quality and noted for the brief inclusion of Purple Rain within Comfortably Numb. On sale at the show were a couple of special items, with all proceeds going to the TCT (Teenage Cancer Trust).

First was a very limited edition poster - just 100 copies, signed and numbered by the artist Pete McKee. The poster design for each major artist appearing during the series of 2016 shows was created by McKee, who was also responsible for the 2016 TCT concert shirt design. The other item specific to David's show was a special black t-shirt, showing birds in flight from the Royal Albert Hall.

Limited stocks of both items have just been made available to purchase from the charity's own website, while stocks last, whilst helping an excellent charity. Click the thumbnails on the right to see them in more detail, and place your orders through the following links:
