Hi Guest is it easy to check copyright, my reason for asking is purely curiosity because my grandfathers songs, sketches and ventiloquists stage doll all got lost at the Clydebank blitz.
My mother used to sing a song that she said he sung which was copyrighted by a well known Scottish personality some time later when Mozart and Allen produced a sheet music arrangement in 1959, my grandfather died in late 1942 6 months after the blitz.
