I have been doing some more sorting of old photographs and have unearthed the attached picture of the CCF band taken by the local press on, I think, the occasion of the Porchester Carnival in 1965. You might perhaps wish to put this on the OPs website.
The Drum Major is myself, the Drum Sergeant is Walker and the out-of-step fifer in the centre looks like D.G. Thomas. I cannot recall the names of the rest - no doubt others can!
