Barry Gibb harmonizes with Barry Gibb — er, Jimmy Fallon — on 'Tonight'

/ Source: TODAY

Who could do perfect two-part harmony with Barry Gibb better than ... well, Barry Gibb?

How about Jimmy Fallon as Barry Gibb?

That display of smooth, harmonious singing showed up on "The Tonight Show" Wednesday as Gibb, of the Bee Gees, joined Fallon for a round of "Silhouette Singing."

In his later years on "SNL," Fallon impersonated Gibb as the manic, abusive host of his own talk show.

On "Tonight" Wednesday, the two men stood in darkened profile and each sang half of a word or phrase, then harmonized it together beautifully.

It was hilarious — the words and phrases were fall-themed, including "scarecrow," "corn maze" and "horn of plenty."

They even managed to include "Trick or Treat, smell my feet, give me something good to eat!"

And on Thursday Gibb stopped by the TODAY studio to perform a couple tunes: the Bee Gees' classic "Jive Talkin'" and his new tune, "In the Now." Check it out!
