Just imagine the Rolodex of Dave Grohl. Two nights ago at their show at New York's Citi Field, Foo Fighters brought out Red Hot Chili Peppers' Chad Smith for a cover of The Faces' "Stay With Me." Then last night (July 16), at the same venue, the call went out to a couple of members from punk icons Bad Brains.

As can be seen in the fan-shot videos above and below, Foo Fighters members Dave Grohl and drummer Taylor Hawkins got to rock out with Bad Brains' Darryl Jenifer and Dr. Know in front of the crowd at New York's Citi Field.

"I would like you guys to share with me the greatest f---ing moment of my f---ing entire life right now," said Grohl, before introducing Darryl and Doc. And as we know, Grohl grew up in the Washington, D.C., area influenced by the punk sounds of what Bad Brains were putting down while getting a start in the band Scream way before Nirvana took off.

Grohl invited the Bad Brains members to get a closer look at the crowd, but then joked, "Watch out, don't fall. Don't fall off the stage," referencing his recent broken leg. The collective of Grohl, Hawkins, Jenifer and Dr. Know then rocked out "How Low Can a Punk Get," seen in the fan shot video above, and "The Regulator," seen in the fan shot video below.

What will the Foo Fighters do next and who might get the call to join them onstage? Only time will tell, but there's still plenty of shows left on their North American tour. Dates can be found here.
