In 1972, he appeared in the musical "Trelawney", with which the Bristol Old Vic reopened after its refurbishment. It proved a great success, transferring to London, first to the Sadler's Wells Theatre and later to the Savoy Theatre. Richardson played the hero, Tom Wrench, a small-part player who wants to write about "real people". He had a song, "Walking On", lamenting his lack of scope in the company, in which he explains that as a "walking gentleman" he will be forever "walking on", whilst Rose Trelawney will go on to be a star.
