Wow! Frank Gorshin in G & S, I seem to remember him doing a very creepy Peter Lorre impression.
Older UK readers may be interested to know that Tommy Handley auditioned for the 'patter' roles with Doyly Carte in 1938.(He was a very good light baritone).
They were going to offer him the job, but by the time they got round to it he had gone on a Music-Hall tour with a sketch called 'The Dis-orderley Room'. WW2 with no ITMA? We would have lost!
