I now have these 3 diaries, 1937, 1944, 1945. Details:
36 Bolton Rd.
My guess is that he was probably born in 1922 or 1923
He was having drum lessons while still at school.
Entry for 24 June 1937; 'left school'
Entry for July 1937; 'started in service department' (probably Lever's).
He was still having drum lessons, but was now regularly playing in a band.
In 1944, he belonged to the Liverpool Amateur Photographic Association.
There are several occasions when he played at "Clattabridge", unusual spelling.
If any of this rings a bell with anyone, please let me know. I'd be happy to return these to the family.
