"Maybe it's because I'm a Londoner" always reminds of Max Bygraves a Cockney entertainer who I often heard on the radio in the late 1940's as a child. It was often sung, straight for a change, in the Royal Navy and not just by Londoners. (Yours truly, for instance even though I came from Worcester). As the title suggests, this one-verse pub song is an inane ditty on loving London, merely because the singer happens to be a Londoner. The song was written by Hubert Gregg.The version I now sing is taken from 101 Pub Favourites for Buskers.
A full version may be found in 70 years of Popular Music, 1940s, Pt. 1.
