George Clooney Shows Off His Pipe(s)

Between the Bah Bah Bah of Sweet Caroline and the adopted patriotism of America, everyone has sung along with Neil Diamond!

But most people don't get to sing along with Neil Diamond! Luckily for George Clooney , he isn't most people!

Ch-ch-check out the video (above) to see- and hear- the Ocean's 11 star duet with the legendary singer!

The actor may be singing about Caroline but it's his aunt jazz singer Rosemary Clooney that he makes proud!

So good! So good! So good! So good!
