The radio programme was a mixture of fast-moving skits, impressions and sketches, linked by snatches of the band's signature tune "We Are the Grumbleweeds". Recurring sketches included 'Trouble at T'Mill' (a comedic parody of a working-class drama set in a Yorkshire mill at the turn of the 20th century), 'Oh Amanda' (a romantic soliloquy performed by Colvill to his fictional partner Amanda with a suitably humorous punchline) and a parody of Radio 4's "Book at Bedtime", where a soft-spoken narrator would attempt to read a story in spite of mounting technical problems such as constantly failing transmitter power, and would end the sketch yelling at the top of his voice in order to be heard. A regular "Family Grumbleweed" sketch introduced the residents of Grumbleweed Towers and a revolving cast of assorted friends, neighbours and lunatics. The programmes were predominantly broadcast on BBC Radio 2 between 10pm and 11pm, with repeats on weekend lunchtimes.
