Long before he found fame - and fame found him - Bill (Diz) Disley was a member of a singing act, the Godfrey Brothers, who played a summer season, I think in the mid-50s, in my father's show, The Starlights at Morecambe's Central Pier.
He was new to the performing game but always eager to learn but what shone through even then was his brilliance on the guitar.
He practiced all the time in his dressing room and was obviously driven by a desire to succeed and succeed he did. On top of it all, he was such a nice guy.   
Nobody at that time realised we were in the presence of true musical genius.
