Regular viewers of “The Colbert Report” know that when musical guests drop by the show, Stephen Colbert isn’t content to sit there asking question: He likes to sing along.
In recent months Colbert has performed alongside Bonnie Raitt, Placido Domingo, Toby Keith, Harry Belafonte and Elvis Costello, to name just a few. So when country legend Dolly Parton sat down for a chat with Colbert to plug her new book, “Dream More,” it was all but inevitable they’d sing a duet.
Of course, there was some small talk first. Colbert fessed up to having a crush on Dolly back in the day, and the stars, both raised in enormous families, competed to see who could name all their siblings the fastest (Colbert won by a hair).
