Thanks, Codger. No, Bert was no sort if instrumentalist ~~ or are you making a norrible pun on 'et al'?! Jim Bray was the one I couldn't remember -- or, culpably, take the trouble to go downstairs to check! And of course it was Alf, not Ali, on concertina. Otherwise I got it spot-on, didderneye! 1 out of 3. Cor!
