Life is short, short, brother!
Ain't it the truth?
And there is no other
Ain't it the truth?
You gotta rock that rainbow while you still got your youth!
Oh! Ain't it the solid truth?

"Ain't It the Truth" originally written for Cabin in the Sky (1943), but pulled from the show, and later included in Jamaica (1957) - Lena Horne version
