Girl:

Speak to us, oh beautiful one, tell us how you make that

glorious sound, that even now an anticipation of it has

reduced me to a snarling, raging, panting, jungle beast!

Birdie:

You gotta be sincere! y really y sincere

You gotta be sincere!

You gotta feel it here,

'Cause if you feel it here,

Well, then you're gonna be honestly sincere!

If what you feel is [bad word]

Make them feel it too,

Write this down now

You gotta be sincere,

Honestly sincere!

Man, you've got to be sincere!

If you're really sincere,

If you feel it in here

Then it's gotta be right!

Oh, baby! Oh, honey!

Don't even have to try,
