A bit late to this thread but I found that the Teesside Fettlers recorded an album in 1983 called "Silk On Steel" using the name Anvil, with the lineup of Stewart McFarlane, Bob Skingle and Adrian Beadnell. It seems it was only put out on cassette (I am after a copy if anyone has one). If the album was release in 1983 that might explain why they are introduced as "Anvil" on that 1985 programme. Also there is just 3 members of the group when on previous albums they recorded with 4.
