A spokesman said: "Addison will be fondly remembered by all whose lives he touched as a devoted mentor, a dear friend and an unforgettable character. He will be sorely missed.

"He leaves behind a proud legacy in his tireless charity work, initiating and organising the annual Channel 4 Comedy Gala in aid of Great Ormond Street hospital. It was his dearest wish to raise enough to fund the opening of a brand new wing of the hospital, a goal that is now in sight."
