The Doormouse, Hare and Hatter.
In his own quiet way, Bird quite steals the show, which led me to recall him doing the exact same thing in Monty Python's JABBERWOCKY (1977), where he does a brief turn as a long winded king's herald who gets quickly beheaded. Bird made me and my friend Mike Gillett laugh so hard we went back to see the highly uneven film several times just to see him. Mike even did a caricature of him for class at Art Institute of Pittsburgh.
I don't know much else about John Bird, but he does seem to be one of the least celebrated of the UK's many funny people. Undeservedly so too.
