In an awesomely unexpected duet, Roger Waters and Eddie Vedder performed "Comfortably Numb" at the 12-12-12 Concert For Sandy Relief last night.
Pink Floyd's former frontman welcomed the Pearl Jam rocker for a rendition of Rogers' 1979 hit, one of many from his band's iconic double album The Wall.
Watch their crowd-pleasing performance below:
Performances from New York-New Jersey area heavy hitters Billy Joel, Bruce Springsteen and Bon Jovi helped raise $30 million from ticket sales alone.
That's before the marathon concert's telethon raised countless millions more, a wonderful and necessary feat as the region recovers from Hurricane Sandy.
In her surprise appearance last night, Kristen Stewart informed us that New Jersey alone sustained $37 billion in damage from the late October storm.
Rogers and Vedder weren't the only surprise duet of the evening. Coldplay's Chris Martin and REM's Michael Stipe joined forces on "Losing My Religion."
Oh, and Paul McCartney stood in for Kurt Cobain for a Nirvana reunion of sorts, joining surviving members Dave Grohl and Krist Novocelic on stage. Unreal.
