Simon's starred in a thousand and one things, most recently Radio 4's hit impressionists series, Dead Ringers.
He's also had his own radio specials, guested on a vast range of BBC and local radio shows and provided a mountain of trailers and voices for shows too many to mention (and mostly forgotten).
Here's a list of some of his stuff.
