Well, that was a pleasant surprise. When I saw that Bruce Springsteen was going to be on The Late Show With Stephen Colbert, I knew he would be talking about Renegades, his new book with Barack Obama. And I figured he’d probably mention the No Nukes concert film. But I had no way of knowing that he would close the show with a solo acoustic performance of The River, which he debuted during the original event in 1979. So that was a treat. But it wasn’t the only late-night treat on the air Monday. You also had bluegrass master Billy Strings (now entering his Dwight Yoakam period, by the looks of things) tearing through the magnificent Red Daisy on Jimmy Kimmel Live, and Leon Bridges offering the soulful Blue Mesas on The Late Late Show With James Corden. So there you have it: Sometimes good things really do come in threes. And two of them come in cowboy hats.
