Les McQueen (Gatiss) is former rhythm-guitar player for 1970s glam rock band Creme Brulée (and still has plenty of copies of two of their albums: Just Desserts and Another Helping).
McQueen is one of the more 'normal' inhabitants of Royston Vasey (when compared to other much more bizarre characters such as Tubbs, Edward and Papa Lazarou), as well as one of the more tragic characters.
