This is Dave's school cadet force band brought up to date at his 50th birthday party in 2001.

Amazing the way Dave and Tim haven't gone grey isn't it?
Must be the music that keeps us so young looking... or L'Oreal

back...

...and from even further back...

This is May 1963 and is a detail from one of those long school photos. Tim joined the school a little later so isn't there.
