Thanks to Bradfordian for the tip about the re-run of the programme: I downloaded it to iPlayer, but as many of you will have found, there have been serious glitches lately with iPlayer, ever since the last update to Adobe Air. I believe the BBC's tech gurus are trying to sort it: advice given on their Help page and in various forums is beyond me, apart from uninstalling and re-installing BBC iPlayer desktop and Adobe Air.
Anyway I went to play the programme tonight and it just said "there has been an error with this download" after showing the initial screen, and the rest vanished, as also did Jools Holland.
One that I downloaded last night was OK, so hopefully the glitch has been fixed - Manran at the Hebridean Celtic Festival: nice young and very talented folk with a largely young audience!
