Beniphone
It may bear my name, but I can't remember what the Beniphone was. When questioned, Gerard says, 'I only have the vaguest memory, but there is a strong aura of abject spanner. I think it was a Fest-period attempt at some kind of improvised glockenspiel/xylophone. I have a Christmas card from you where it is mentioned." So there you go. (Ben)
