Daniel Keith Swain, (b. August 18, 1983) known mononymously as Danny!, is an American singer-songwriter, record producer, composer and voice actor.
Swain rose to prominence shortly after his debut performance on Late Night with Jimmy Fallon, where he premiered his single "Evil"; he subsequently began a side career in voice acting, narrating the fifteenth season of ESPN's Hey Rookie, Welcome to the NFL. Swain appeared on Sesame Street that same year.
