[It goes]
Daddy dear, daddy dear, is the world really round?
Do the bluebird you seek will surely be found
And the time da da da
And if children could fly
There'd be no need for birds
No need for birds
[Forgot the darn song. It's really nice. It goes]
Daddy dear, daddy dear, is the world really round?
Da da da, da da da, da da da na na found
[And it goes]
Daddy dear, daddy dear, is the world really round?
Da da da, da da da, da da da na na na
[Then it goes]
Little one …
[And a guy in the background comes, and he goes]
Little one, oh little one, yes, the world's really round
And the bluebird you seek will surely be found
And if children could fly
There'd be no need for birds
[And it goes]
‘Cause on the day you were born
There's do do do dum
[Something like that]
(Composer: Wayne Shanklin)
