Russell Crowe Sings On The Tonight Show

So another A-List Celebrity graced the set of The Tonight Show with Jimmy Fallon, it was Russell Crowe!

He sang Folsom Prison Blues, who knew he could sing like that?  And to top it off Jimmy Fallon, can play a mean harmonica?!  This is definitely worth the watch!

Have you ever seen someone sing or play an instrument that didn't just surprise you, but blew you away?
