Melvyn Hayes
From Tardis Wiki, the free Doctor Who reference
Melvyn Hayes (born 11 January 1935) played Wilkin in the webcast version of Shada, as well as its audio release, and the Scorchies in AUDIO: The Scorchies
Wilkin was played in the original television version of Shada by Gerald Campion. When recasting the late Campion's role for the audio/webcast version director Nicholas Pegg remembered that Hayes had appeared alongside Campion in the Billy Bunter television series, upon which casting Hayes as Wilkin became "irresistible."[1]
Hayes is the former husband of Wendy Padbury and the father of Charlie Hayes.
