Hi there...going right back to the original question, re the members...I have a copy of their "Rum & Raspberry" 7" EP which lists the members (as most of you already know) as being:
CHRIS BETTLE
TONY BRITZ
BARRY GOANNA GOLDING
MARSH ROBINSON
PETER HOWELL
LIZ EAGER
CLIVE WILLMAN
However the cover is fully signed by all EIGHT members, of some time after this of course...being Chris, Tony, Barry, Liz, and Clive (no Marsh or Peter H.)...and the other 3 who signed are:
ANNE O'CONNELL
GEOFFREY O'CONNELL
and LIONEL O'KEEFE
A clue to the timeframe is that Barry has added after his signature "Thanks for the bunk in '75"...suggesting, one would assume, this was signed at least 2 or 3 years later. All have signed in the same pen - it was signed all at one time...at a gig in Lismore (I got this from a chap up there).
So that's my input...hope it helps a bit. Cheers, Jules
