Colin Sell Colin Sell Colin Sell (born 1 December 1948) is a British pianist who has appeared on the radio panel games "Whose Line Is It Anyway?" and "I'm Sorry I Haven't a Clue". He has become famous mostly for his long service on the latter show, where the opening credits are "At the piano is Colin Sell, and your chairman is Humphrey Lyttelton/Jack Dee", in the manner of the show none of the panelists are credited in the opening credits, but are introduced by the chairman, usually in a sarcastic manner ("the foremost available comedians.

I'm Sorry I Haven't a Clue elbow". More puns are found in the "Arrivals at the Ball" section, of the form "Mr and Mrs X and their son (or daughter)..." the child's name forming a pun, preferably laboured and feeble. This grew out of the "drama" section of later shows in the "I'm Sorry I'll Read That Again" series, for example, at the Criminals' Ball, "Mr and Mrs Knee, and their Swedish son, Lars Knee". According to Tim Brooke-Taylor twenty per cent of the show is ad-libbed. According to Willie Rushton, it is more like fifty per cent, but he didn't think that a bad thing.
