Heavy Pettin' were almost the next big thing and one of the best Hardrock bands to ever come out of Scotland, UK, during the 80's. They hit instant success with their debut album "Lettin' Loose (1983)" and continued to release marvelous music with "Rock Ain't Dead" in 1985. You can finally find them on CD, reissued through Majestic Rock, and here's a short interview with guitarist PUNKY MENDOZA.
These are photos from concerts where Heavy Pettin played, so they may be of other bands that played the concert as well.
