When [Gary P. Nunn] landed in Austin in 1967 to study pharmacy at the University of Texas, he presaged the “cosmic cowboy” movement to come. After Willie Nelson, Michael Murphey and Jerry Jeff Walker all moved to town, Nunn was such a pivotal figure on the scene that at one point he was playing bass with all three artists. His talents on keyboards and vocals were also heard on many of the legendary albums from that era.

While in London recording Murphey’s Cosmic Cowboy Souvenir album, [Nunn found himself] wishing he were back in Texas, prompting him to write “London Homesick Blues.” [It became a breakout hit on] Jerry Jeff Walker’s landmark ¡Viva Terlingua! album.

In addition to the many gold albums on which he has played and/or written and published songs, Nunn has earned a number of notable awards and honors over the years. He was named an Official Ambassador to the World by Texas Governor Mark White, and years later Governor Rick Perry also declared him an Ambassador of Texas Music. In 2004, he was inducted into the Texas Hall of Fame.

“The thing I’m proudest of is being a member of the West Texas Walk of Fame in Lubbock with Buddy Holly, Waylon Jennings, Bob Wills and Roy Orbison — guys who were my heroes.”
