As previously reported, this week, Pink Floyd guitarist David Gilmour made a fascinating guest appearance in a special BBC comedy production, which aired on BBC2 TV.

The production was an attempt to re-trace the journey up the Thames immortalised by Jerome K Jerome in his classic Three Men in a Boat. The three comedians taking part came across David's houseboat recording studio, The Astoria, early on their first day, and decided to play a visit.

David, ever the affable host, gave them a guided tour of the boat and even played an excerpt of a work-in-progress track to the trio - "Smile". Many of you will recall that this received its debut at David's Meltdown concert in London, in 2001. Five years later, very little has changed in the song - still a beautifully mellow, drifting love song.

We'll keep an eye open for a repeat of this show for all those who missed it. In the meantime, below are a number of screen shots from the programme, to give you a good flavour of what it entailed. And for all of you who have written to ask, we will not be making the sequence available for download from this site, as it is a copyrighted item - apologies.
