Ian, the guy in the door reminds me of Mac Rebennack.
And it looks like you had Jack Black on the right

.... But I guess you didn't play any Tenacious D back then.
Nope, no Tenacious D back then, Nigel..ha ha!
John "Hubba" Parris was his name...great vocalist and also played congas, cabasa, and rhythm guitar...the guy sitting down with the 'shades on was the other lead vocalist, who also played guitar and harmonica...in fact, we all sang.
Those guys were like family to me, Nigel, and we still have remained close friends after all these years.

BTW Nigel, that's the first time I saw a guitar Leslie being used was with this particular band, as Bo had one in his bag of tricks...perhaps you might know the particular model...it had a black Tolex cover and wasn't very big, about half the size of one of my Leslie 147RV's. I think it just had one speaker.
