They are all bands I have heard of, but I only know the odd song by them. I think Wheels of Steel was the big hit for Saxon. I used to listen to the Friday Rock Show with Tommy Vance on Radio 1 back in the day and you would hear this stuff. The metal scene has changed since then.
I expect there was a lot of denim and leather in the crowd and probably lots of patches on jackets. Was it mostly older guys? These bands are getting old and may not have many gigs left in them.
Rock on!
