I didn't know that. Try this for size... Not easy.
OK, two original tunes written and recorded by former Lotus owner/racer Chris Barber and his band, with a motoring theme, pre 1975.
OK - you give up. The first was called "Cortina Run" and the second "Brands Hatch" - where the band played after at least 1 F1 GP. I also remember them playing after a Mallory Park meeting on the smallest stage I have ever seen. About the size of four wooden pallets!
