Editing I'm Sorry I Haven't a Clue (section)

===Musical accompaniment===
Early episodes featured Dave Lee, who provided piano accompaniment on ''[[I'm Sorry, I'll Read That Again]]''. However, [[Colin Sell]] now usually fills this role. He is often the butt of jokes about his musical ability, to which he is unable to respond as he has no microphone.<ref>{{cite web|url=https://www.bbc.co.uk/comedy/clue/interviews/colin_transcript.shtml|title=Interview with Colin Sell|publisher=BBC}}</ref>  For example: "When music experts hear Colin's compositions, they say he could have been another [[Irving Berlin|Berlin]], [[Cole Porter|Porter]] or anybody else employed by the German State Railway." Guest pianists are called in when Sell has been unable to attend (or the ''ISIHAC'' team have "won the coin toss" as Lyttelton once said on the show), including [[Neil Innes]], [[Denis King]] and Matthew Scott. Lyttelton's band also appeared on a couple of Christmas specials.<ref name="people" /> On one occasion when Innes was guesting, Lyttelton outlined the musician's career, concluding that this "has brought him to where he is today: standing in for Colin Sell." In another appearance Innes sang along to his own composition "[[I'm the Urban Spaceman]]" during a round of "Pick Up Song".<ref>{{cite episode | title=I'm Sorry I Haven't A Clue|series=I'm Sorry I Haven't A Clue | station=[[BBC Radio 4]] | airdate=1997-11-15 }}</ref>

The theme music is called "The Schickel Shamble", by [[Ron Goodwin]], and is from the film ''[[Monte Carlo or Bust!]]'' It was chosen by David Hatch.<ref name="tim barry graeme" />
