The BBC have not put City Salute on iplayer.  As it was a BBC outside broadcast I can't think why not and I am not the only person loking for it.There is some rather nice video on You Tube taken by a young man I believe to be Brazillian. He couldn't quite get his camera up to the Golden Gallery above the dome to see where the lone piper was playing but he got quite a lot else. Lots of cheers and union flags waving. Well done that man.
The piece read by Ross Kemp was, according to a comment on ARSE the unofficial Army blog, taken from Viscount Slim's memoirs Defeat into Victory: Battling Japan in Burma and India, 1942-1945.
