A contribution from a pedant:-
[First Prize: Lee Nicolson; No Prize At All: MGM]

He was Lea Nicholson with an "h" and he took his first name by shortening his middle name "Leatham".

I ran a weekly club with him in Brighton from 1968 - 1970 and though he had a good reputation as a singer and musician, I reckon that he was seriously underrated in both departments. He was a truly original inventive concertina player.
Moved away from folk song into electronica. Last spotted playing bass guitar in a band in the Derby area.
