I bought a cassette in about 1985 at one of Steve Gibbons gigs at Villiers Hotel (I think).
It`s called Tried & Tested.
Track list for side 1:

1. BSA

2. Harley Davidson

3. Motorcycle Song

4. Triumph Bonneville
Every track is a cracker!
Steve was a great supporter of the TT and got involved in sponsorship for a while. Haven`t seen him over there for a while.
Another great band and supporter of the TT is Bob Fish (Johnny & The Roccos). Fantastic 50`s rock & roll band from Hawick. Remember seeing them at The Majestic a good few years ago. Before it got knocked down for housing.
