As Foo Fighters’ tour rolls on, they once again welcomed out a special guest last night in Noblesville, IN as Blues Traveler’s John Popper joined them on harmonica for a jam out of their original “This is a Call.”

Popper wrote on his Facebook page that the show marked his first time seeing Grohl and the Foos, saying, “Long on my bucket list, they are such a great band and a great family.” Popper also said he gifted Dave Grohl’s daughters with a harmonica of their very own. In the same post, Popper says he also sat in with Bruce Hornsby in Asheville, NC.

Foo Fighters’ tour has been highlighted by several special guests, as they previously welcomed out members of Bad Brains, Red Hot Chili Peppers drummer Chad Smith and others.
