You're The Happy Song I Sing

I walk around hummin' the same song every day
And folks they hear me comin' oh a half of the block away
But I never worry about that kind of thing
Cause you're the happy song I sing

I hear the Mr Bluebird when he's a singin' it out
I doubt if that bluebird's got more to sing about
And no matter what 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
But I got all that happiness your loving can bring
Some people may wonder just what's causing the change
This spell that I'm under has got me acting strange
But it's just that old feeling that only love can bring
And you're the happy song I sing
[ whistle ]
The way that I'm feeling why shouldn't I sing....
And you're the happy song I sing
