John Mayer helped celebrate Dick Boak's retirement from renown American guitar manufacturer Martin Guitar on Saturday night (Jan. 6) with the help of other artists including fellow guitar icon Steve Miller

In an experience that Mayer described as "unreal," he shared the stage with Miller to sing The Steve Miller Band's hit "The Joker." 

"I got to play with Steve Miller (and some other incredible guitarists) on one of the greatest rock songs of all time, “The Joker,” Mayer shared to Instagram. "Retirement concert for the incomparable #dickboak who worked many years at @martinguitar putting the best acoustic guitars in the hands of artists all around the world. Love ya Dick, happy trails."

The concert, which also featured other artists such as Marty Stuart & His Fabulous Superlatives, Laurence Juber and Jorma Kaukonen among others, was a celebration to honor Boak and the legacy he left behind for all artists he worked with.
