A fond memory from childhood is watching Clive Dunn playing a character called Charlie Quick, aka Grandad (1979-1984).
I just discovered that he played a character with the same name in 1957. Presumably the same character, but I can't find any confirmation. 1957 show : THE ADVENTURES OF CHARLIE QUICK.
As far as I can tell, this was a 10 minute segment on 60 minute magazine show STUDIO E.
Lostshows lists TAoCQ as "missing, believed never to have been recorded" however, it lists Studio E as existing complete.
