Frost is known for his work in the 1980s with Mark Arden as part of the double act The Oblivion Boys on Saturday Live. Veterans of the alternative comedy scene, he and Arden appeared in The Young Ones, and later had their own TV series Lazarus and Dingwall on BBC2. They played the lead roles in the 1987 revival of Tom Stoppard’s play, Rosencrantz and Guildenstern Are Dead at the Piccadilly Theatre.
The duo appeared in a series of British TV advertisements ending with the catchphrase “I bet he drinks Carling Black Label”. One spoofed the “launderette” commercial for Levi’s in which Nick Kamen stripped to his underwear; in their pastiche, Arden and Frost played launderette customers who were stripped entirely, with just strategically placed books maintaining their modesty.
Without Arden, Frost has appeared on Radio 4’s Just a Minute, and the improvisation show Whose Line Is It Anyway?. He has appeared on three episodes of Have I Got News for You (there was a 13-year gap between his second and third appearance) and on Never Mind the Buzzcocks. He also appeared as Dirk in Tony Bagley’s series Married.
He played two small roles in Blackadder. The first in “The Witch-Smeller Pursuivant” in the first series (The Black Adder), as a prison guard. The second in an episode of Blackadder Goes Forth: Corporal Punishment) as the overly-cheerful head of a firing squad sent by a court martial to shoot the lead character, played by Rowan Atkinson. He has worked consistently as a jobbing actor in British television.
He also had a cameo in the British comedy series Mr. Bean, starring Rowan Atkinson, in the episode entitled “Mr. Bean Rides Again” in one of the skits where Mr. Bean is riding a train.
Frost is resident compere at the East Dulwich Comedy Club and a regular on the London comedy circuit. He is also a veteran of the Edinburgh Fringe and Glastonbury Festival.
In 2003 he appeared in Guy Masterson’s sell-out production of 12 Angry Men alongside Bill Bailey.
Frost was born in Cornwall and is the son of the late abstract artist Sir Terry Frost and brother of painter Anthony Frost.
Frost still appears regularly with Comedy Store Players.
