I used to play in a blues band which would borrow its horn section from various members of a local big-band-jazz oufit.
On one occassion a well known tenor-sax player turned up and announced that he was the stand-in for our regular player.
It turned out that his gig in Germany with "M-People" had cancelled and, as he said himself, he would rather come out and play for a tenner that stop home.
The same guy recently played for Elton John in Brussels!

C-flat.
