Leon Redbone

While his gravelly baritone and omnipresent fedora, dark glasses and Groucho Marx moustache made him one of the more distinct and recognizable characters in popular music, little is known about the neo-vaudeville crooner Leon Redbone. He made his recording debut in 1976 with On the Track, which featured legendary jazz violinist Joe Venuti as well as singer/songwriter Don McLean; his 1977 follow-up Double Time even reached the U.S. Top 40 charts, largely on the strength of his frequent appearances on television's "Saturday Night Live." He performed the theme song for the popular 1980s sitcom Mr. Belvedere, as well as Your Feet's Too Big, the theme from the syndicated sitcom Harry and the Hendersons. He appears regularly on the PBS children's show Between the Lions. He did a cover of Frank Loesser's romantic Christmas song Baby, It's Cold Outside with Zooey Deschanel for the closing credits of the 2003 film Elf. He also voiced the character of Leon the Snowman in the same film.
