After seven seasons on "The Late Show," Stephen Colbert announced that bandleader Jon Batiste is leaving to pursue other interests.

"For the past seven years, we've had a front-row seat to Jon's incredible talent. And will he be missed here? 

Yeaaa!' But we're thrilled for you, Jon, and I can't wait to have you back as a guest with your next smash hit "According to Colbert.

"Louis has done an excellent job this summer, but he is very humble, so he will not say so.

Give him an afternoon and he'll teach you how to play Mozart with a shoehorn "According to Colbert.
