>> HEY, STEPHEN.

>> Stephen: SO WHAT ARE YOU DOING?

>> AH, JUST CLEANING UP THE OLD BANJO FOR THE SHOW.

IT IMPROVES THE TONE.

>> Stephen: I WOULD NOT HAVE THOUGHT THAT.

>> OH, YEAH, YEAH.

IT'S AN OLD PROFESSIONAL SECRET.

>> Stephen: OH, WOW.

>> IT'S REALLY BEEN GOOD.

>> Stephen: ANYWAY-- OH, I DIDN'T KNOW YOU PLAYED THE

GUITAR, TOO.

>> I DON'T.

THIS IS OUR GUITARIST'S GUITAR.

HE'S GOING TO BE REALLY SURPRISED.

>> Stephen: OKAY, YEAH.

>> YEAH.

>> Stephen: DO YOU DO THIS A LOT WITH INSTRUMENTS?

>> I DO.

YOU KNOW, I WAS AT A CONCERT HALL RECENTLY, AND THEY HAD THIS

BEAUTIFUL GRAND PIANO.

AND I REALIZED, THIS THING HASN'T BEEN WASHED IN ABOUT

THREE YEARS.

AND SO I GAVE IT A GOOD HOSE-DOWN.

>> Stephen: DID IT SOUND BETTER?

>> AH, DON'T KNOW, BECAUSE I WAS ASKED TO LEAVE.

BUT ANYWAY-- >> Stephen: ANYWAY, HAVE A

GREAT SHOW.

>> BUT YOU KNOW WHO ELSE LOVED IT IS WHEN I WASHED YO YO MA'S

CELLO, AND HE WAS SO GRATEFUL.

>> Stephen: YOU WASHED HIS STRADIVARIUS.

>> OH, A STRADIVARIUS.

So, IT'S, LIKE, 300 YEARS OLD, SO REALLY DIRTY.

SO NO WONDER HE WAS SO GRATEFUL.

HE LOOKED AT ME WITH TEARS OF JOY.

IT WAS SO NICE.

( LAUGHTER ) ( PLAYING OFF KEY )

>> Stephen: ANYWAY, GREAT TO SEE YOU.

BREAK A LEG TONIGHT.

>> HEY, STEPHEN, STEPHEN.

>> Stephen: YEAH.

>> WANT ME TO GIVE THOSE GLASSES A GOOD CLEANING FOR THE SHOW?

>> Stephen: UH-- >> IT HELPS.

>> Stephen: SURE.

YEAH, SURE.

>> NO, YOU CAN LEAVE THEM ON, THAT'S FINE.

THERE YOU GO.

>> IT'S "THE LATE SHOW WITH STEPHEN COLBERT."
