Thanks, (wheeze), Steve, for your consideration. There was Borra Minevich mentioned in the Geldray and Adler threads and the Morton Frazer Harmonica Gang who used to feature on variety bills (Yes, I remember variety!) and others whose names I've forgotten. Usually there was a person of restricted growth who played an exaggeratedly large harmonica and a big guy who played the glh (great little harp). BTW ,on the Goons tribute programme Max's role was played by Harry Pitch who is still active with jazz and big bands in S.E. England.
Ooops, too much excitement, NURSE, the screens!
