The support act was a short lived glam rock band called 'Girl'.
I'll have to do more digging to find out where I saw Van Halen. I didn't think it was The Rainbow, but maybe it was.
[Edit]
Van Halen could have been June 1978 when they supported Black Sabbath.
Unlike you groovy (no-doubt sharp-dressed) dudes I didn't see them until they were global superstars, following Eliminator!
But it was quite a cool gig for me: my big sis was wheeling me around with both legs in casts following a nasty car-crash.
