I have just seen this photo and can add a few names. You are correct, the bass drummer behind Doc is Chris. Fulford. The chap on Doc's right (the drum major with the cane) is Paul Tipple, the chap in his right (in the Naval Cadet uniform) is Derryck Tweedley. I am on the other end of the front row. I'll wrack my brains for any other names.
