From the wiki: “‘The Ballad of Davy Crockett’ was introduced on ABC’s television series Disneyland, in the premiere episode of October 27, 1954, sung by The Wellingtons but performed on-screen by Fess Parker, playing the role of Davy Crockett, accompanied by similarly attired musicians. The song would later be heard throughout the follow-up Disneyland television miniseries, Davy Crockett, first telecast on December 15, 1954. The Wellingtons were originally called The Lincolns, and recorded for Kapp Records. As The Wellingtons, they were signed by Walt Disney to record the theme song for Disney’s The Wonderful World of Color and, subsequently, ‘The Ballad of Davy Crockett’.
“Trivia: Gilligan’s Island producer Sherwood Schwartz, working with composer George Wyle, came up with a Folk song theme song that told the back story of the castaways, and hired The Wellingtons to sing it. The song was a hit. The Wellingtons appear in a second season (1965–66) episode of Gilligan’s Island as a Rock group called ‘The Mosquitoes’.
