Ray Wylie Hubbard On The Late Show With David Letterman Tonight. Ray Wylie Hubbard will perform tonight (Wednesday) on the Late Show with David Letterman. His performance is in support of his 2012 album, The Grifter’s Hymnal. According to the Americana Music Chart, the album was the #8 Record of 2012. “This really was a very special record to me. It wasn’t easy, and some of it really was a struggle, but it was fun. I think each record to me has been a struggle in a way, and I like it that way. I like it that they’re all hard to do, because I think that makes them all have more value to me. It makes me kind of reach for a better part of myself. It keeps me from settling.” – Ray Wylie Hubbard Don’t miss Hubbard’s performance on CBS at 11:35 p.m. ET, PT & 10:35 p.m. CT.
