He'll be forever associated with Jimmy Page. But Robert Plant's memorable onstage collaboration with Justin Adams at Mountain Jam 2015 proves all over again what a great bandmate the former Led Zeppelin frontman still is.

Watch as Plant, appearing with Adams on "Funny in My Mind (I Believe I'm Fixin' to Die)," surrenders the spotlight for the guitarist's rockabilly-infused solo during his June 5 performance. It's clear how much fun Plant is having as he joins the crowd in marveling over Adams' out-sized swagger. Watch the above clip to see just Adams' solo portion of the song.

Their musical relationship was forged over multiple solo projects, beginning with 2002's Dreamland and continuing through subsequent Plant efforts like 2005's Mighty ReArranger and 2014's lullaby and ... the Ceaseless Roar. Adams and Plant shared co-writing credit on "Funny in My Mind," Dreamland 's opening track and a rewrite of Delta bluesman Bukka White's "Fixin' to Die Blues."

Plant also mixed tracks from lullaby, choice covers and a menu of re-imagined Led Zeppelin classics including "Black Dog," "What Is and What Should Never Be" and "Dazed and Confused" during his Mountain Jam show. Fans who missed out on this stop – which also included sets by Gov't Mule and the Black Keys – can get a sample of Plant's live show as part of his recently released More Roar EP.
