QUESTLOVE EXPLAINS "WALK ON" MUSIC

A lot had been made of how Conan O'Brien had Max Weinberg and the band play very expensive songs in his last week on The Tonight Show last week. Questlove of The Roots, house band for Jimmy Fallon's show, breaks down the science "walk on" music on late night shows - I didn't realize that this was started by Paul Schaffer on David Letterman's show. Read all about it on a very extended Quest tweet.
