Devall's voice was heard across Canada as Jim Perry's announcer on many of his game shows, including "Definition", "Headline Hunters" and "Eye Bet", as well as in Ford television commercials on the popular "Hockey Night in Canada" program. In 1975, Devall was offered a hosting position with ABC's "Good Morning America"; he turned down the offer and remained with CFTO-TV. While at the station, he also served as a continuity announcer, voicing promos, bumpers, program intros and outros, station IDs and the nightly sign-off sequence, most famously backed by the ELO instrumental track "The Whale", and years earlier by Eric Gale's instrumental version of "Killing Me Softly with His Song".
