The Foo Fighters played Maracana stadium in Rio de Janeiro, Brazil last night as part of their Sonic Highways Tour and performed a cover of Rush's Tom Sawyer at one point. You can check out some pro-shot video of the entire concert on YouTube here. The Rush cover comes in at the 1:48:22 mark. They also performed covers of KISS's Detroit Rock City, The Faces' Stay with Me and Queen/David Bowie's Under Pressure (full setlist here). Thanks to Leo S for the heads up and Gustavo M for the video link.
