The voice actor for Ed's spoken lines was Allan "Rocky" Lane, a former B-movie cowboy star. Sheldon Allman provided Ed's singing voice in episodes; his solo line ("I am Mister Ed") at the close of the show's theme song was provided by its composer, Jay Livingston. Allan Lane was alluded to by the producers only as "an actor who prefers to remain nameless." After the show became a hit, Lane campaigned the producers for screen credit but accepted a raise in salary instead.
