Nicks took center stage to duet with Dave Grohl on her 1981 single, "Stop Draggin' My Heart Around", with the guitarist handling Tom Petty's parts from the original version. Nicks then sang "Gold Dust Woman" from Fleetwood Mac's 1977 smash, "Rumours."

The September 21 show was one of two dates the Foo Fighters are playing at The Forum as part of their North American tour in support of 2014's "Sonic Highways."

Grohl continues to perform on a metal throne with his leg in a walking boot as he recovers from a broken leg he suffered during a June 12 show in Gothenburg, Sweden.
