(You're the happy song I sing)
  I walk around a hummin' the same song every day
  Folks hear me comin' a half of block away
  But I never worry about that kind of thing cause you're the happy song I sing
  I hear Mr Bluebird when he's a singing it out
  But I doubt if that bluebird's got more to sing about
  No matter the season for me it's always spring cause you're the happy song I sing
  The way that I'm feeling why shouldn't I sing
  When I got all the happiness your loving can bring
  Some people may wonder just what's a causin' to change
  This spell that I'm under has got me acting strange
  But it's just that feeling that only love can bring cause you're the happy song I sing
  Yeah you're the happy song I sing yeah you're the happy song I sing
