In 1994 Roberts sang on The Listening Pool's (ex-OMD members Paul Humphreys, Martin Cooper and Malcolm Holmes) album "Still Life" on the track "Somebody Somewhere". Roberts played the role of Pop Larkin in the world premiere of "The Darling Buds of May-Perfick". This was a musical based on H. E. Bates' novel "The Darling Buds of May", written by David Burton, formerly a member of the cast of "Only Fools & Horses". The show ran for a week in April 2008 at The Kings Theatre, Southsea as a trial to see whether the company could raise enough interest to finance a West End production. Its level of success is currently unknown.
