Bass player for the excellent progressive rock band Marillion as well as the side project Transatlantic. He's one of the best bassists in the business, for my money, with the best vibes of Chris Squire and Paul McCartney all thrown in.
He's got to be in his early 40s, brown hair, and not that tall (I'd say 5' 5".) Got into a nasty bicycle accident in early 1999.
A really nice guy and someone it's good to share a beer with and talk about music.
