how'd you know it was my birthday...
**It's a hap-hap-happy day
Toodle-oodle-oodle-oodle-oodle-lay
For you and me for us and we
All the clouds have rolled away
It's a hap-hap-happy day
Toodle-oodle-oodle-oodle-oodle-lay
The sun shines bright and the world's so right
It's a hap-hap-happy day
Four and twenty sunbeams
Are dancing round my face
Four score and twenty more
Are dancing every place
It's a hap-hap-happy day
Toodle-oodle-oodle-oodle-oodle-lay
You can't go wrong if you sing this song
It's a hap-hap-happy day**
