As for the Jeremy and Richard being musicians, i remember JC saying Richard could play the guitar and he was learning to play the drums
Yes, I remember that Jeremy said somethink about that band thing in one of his Times articles. His going to play the drums he said."It'll feature performances from Supergrass and Travis, as well as a very special appearance from the Top Gear house band as our three presenters take to the stage accompanied by Justin Hawkins from The Darkness."
Top Gear house band?
