Old gig tickets, Gordon Giltrap

So, it was 37 years ago today (ye Gods) that I saw Gordon Giltrap, supported by Gryphon, playing a gig in my school hall. I have absolutely no idea how it came about, but it really happened, and was pretty good, actually. So, don't believe Wikipedia when it tells you Gryphon split in 1977, as a version of the band definitely played, in Kingston, in 1980.
