(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
