Friendship-ish

This is an affectionate and amusing video from Stephen Colbert's show.  As he says at the beginning, he's a huge fan of James Taylor.  This is a sketch that builds to the two of them singing together.  I don’t want to say anything more.

If you can avoid reading the title of the video at the top of the freeze frame below, it gives away one joke.
