Twomey introduced himself as "a manualist", the first known use of the term in a musical context. He appeared on several other programs including "The Mike Douglas Show" where he performed the "Colonel Bogey March," made famous in the film "The Bridge Over the River Kwai", and "The Merv Griffin Show" where he performed "When the Saints Go Marching In." He provided audio for the Barney Miller episode "The Dentist," first aired December 27, 1979, in which a manualist musician is hauled in for disturbing the peace.
