The entertainer, best known as one third of the popular 1970s show The Goodies, and I'm Sorry I Haven't A Clue, died on Sunday.
Goodies co-star Bill Oddie called him a "true visual comic and a great friend".
The third member of the trio, Graeme Garden, said he was "terribly saddened by the loss of a dear colleague and close friend of over 50 years".
"He was a funny, sociable, generous man who was a delight to work with. Audiences found him not only hilarious but also adorable."
