This free show was filmed for TV broadcast. It was later released on VHS. I was lucky & won a copy of the VHS via a competition from Metal Hammer magazine 🙂 
It was subsequently released many times over on both DVD & Audio CD. The first DVD release was back in 2004, under the title of “Live Legends”. The latest re-release (November 2017) of this show is titled ” 10 Years Of Denim & Leather-Live 1990 ” This has both CD&DVD versions of the show.
