Normally, playing a classic-rock cover song at an arena show is a cheap way of pandering to the mass crowd, but in the Foo Fighters' case Wednesday at Xcel Energy Center it only added value and an exclamation point to the already lengthy proceedings. The band threw a pair of old nuggets into the encore, starting with Tom Petty's "Breakdown," which they coolly blended with their own new howler "Dear Rosemary." Said Dave Grohl, "Every rock singer really just wants to be Tom Petty." That cover was planned, according to the official set list assembled pre-show, but the total rocks-off version of Queen's "Tie Your Mother Down" came out of the blue.

Grohl preceded "Tie Your Mother" with a funny story about Cee-Lo Green asking them to help fill in his allotted set time at a festival. Along with a snarky, "Sure, and how about $50,000?" Grohl's response was to fill in the extra time with a string of covers, including the Queen gem. That they added it here on an already stacked, lengthy night of originals only reiterated how invested they were in the show.
