Jimmy Fallon's week-long tribute to the legendary Pink Floyd continued last night, with Foo Fighters appearing on Late Night With Jimmy Fallon to provide backing support to Floyd co-founder Roger Waters.

Check out the performance below, in which Foo Fighters and Waters unite for a great rendition of "In The Flesh," off the landmark Floyd album The Wall. The Grohl superfans out there will likely feel a bit disappointed, as Dave doesn't even sing backup on the song. The band is entirely there for support of Waters.

Waters also sat for an infrequent interview with a giddy Fallon, reminiscing about the band's early days (with an organ player 40 years their senior) and had a few kind words for the Shins’ cover of Breathe from the previous night.

The rest of Fallon's Floyd tribute week should be interesting, with MGMT, Dierks Bentley and Pearl Jam turning in their own homages to the band. Stay tuned.
