Just found out the date of this from an ebay listing for the limited single they gave away at the gig! I went to loads of Under Neath What gigs but I don't have evidence for many of them...
Met Bam from Dogs D'Amour at this gig I think.
I was at this one, more from this year in my gigography for 1989. Part of the list of every gig I went to from '87 to '19. It's a natural step from my Best Gigs Ever blog post. Yeah I know very geeky, let's let that go though, I'm enjoying reminiscing about this stuff.
