You're the Happy Song I Sing

(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
