While I was up on the mountain at the Music Fest in Steamboat Springs, Colorado, Ray Wylie Hubbard was busy...you know, just doing Letterman. No biggie!

Here is Ray doing the auto biographical song "Mother Blues" on The Late Show.

Ray called into the Slumballou Party after his performance and we chatted about Biff, the food in the green room and about his rock star entourage!

Pretty dang awesome! Speaking of...David Letterman also requested Ray stick around and play "Screw You, We're From Texas"!

Thanks you so much Mr. Hubbard!
