Over the years, iconic Pink Floyd bassist and creative force Roger Waters has done his fair share for military vets and he continued his association Friday (Oct. 16) in Washington, D.C., taking part in the MusiCorps "Music Heals" benefit with a few special guests helping him out.

Waters was joined during his set by Rage Against the Machine guitarist great Tom Morello, Smashing Pumpkins leader Billy Corgan, longtime Hall & Oates and Saturday Night Live band guitarist G.E. Smith, Sheryl Crow, the MusiCorps Wounded Warrior Band and more. As can be seen in the fan-shot video above, Corgan and Tim Donley, a Marine who lost both of his legs in Afghanistan, lend a vocal assist during the chorus of the classic "Comfortably Numb," while Morello and Smith offer some blistering licks.

Morello also appeared with Waters during performances of "Shine on You Crazy Diamond," "Money" and a cover of "The Ghost of Tom Joad." Corgan, meanwhile, guested on "Wish You Were Here," "Brain Damage" and "Eclipse." In addition to the encore of "Comfortably Numb," which can be seen above, Corgan and Morello finished out the night with Waters on a cover of the Bob Dylan classic "Forever Young," which can be seen below.
