The Mockingbird Song, by Inez and Charlie Foxx (recorded by James Taylor and Carly Simon much later)

Isn't that a riff on an old lullaby?

Mock (yeah)
ing (yeah)
bird (yeah)
yeah (yeah)
Mockin'bird, now

Everybody have you heard
He's gonna buy me a mockingbird
And if that mockingbird don't sing
He's gonna buy me a diamond ring
And if that diamond ring won't shine
He's gonna surely break this heart of mine
And that's why I keep on tellin' everybody
Say yeah, yeah whoa, whoa, whoa, whoa, whoa, uh, oh
