[2] Dee has lived his life with a neuromuscular disorder that results in a series of ticks, twitches, and spasms which has created a weakness in his neck.
He attended boarding school in Hertfordshire, where he started playing guitar after hearing Lonnie Donegan's "Rock Island Line".
While working as a gardener, Dee started playing bass semi-pro with a band called The Planets and then returned to the guitar and got a gig backing crooner Steve Arlen.
Eventually, he joined the Laurie Jay Combo who backed the likes of Gary US Bonds, Memphis Slim, John Lee Hooker and Kenny Lynch and his band appeared in Michael Winner's 1964 The System, which starred Oliver Reed.
Dee was a session musician in the 1960s, working alongside the likes of future Led Zeppelin members Jimmy Page and John Paul Jones.
Dee also supported John Lee Hooker on the bluesman's first British shows, produced Les Fleur de Lys (whose line-up included Bournemouth rock alumni Gordon Haskell and Tony Head), backed Elkie Brooks, The Walker Brothers and Carl Perkins, was twice hired by Van Morrison to join Them, and filled in for Syd Barrett in Pink Floyd.
