Foo FightersSonic Highways tour rolls on, and as it does, Dave Grohl and company prove time and time again just what genial folks they are.

At the band's show in L.A. on Tuesday (Sept. 22), Grohl spotted a kindred spirit in the crowd -- a girl who was also sporting a cast due to a broken leg. Instead of his usual "Big Me" dedication, Grohl addressed the song to the young fan, because "nobody wants a f---ing broken leg."

“This one, I usually dedicate to the road crew and the people who built the throne and all that bulls---,” Grohl said to the audience. “I’m going to sing this one for the little lady who broke her leg, too, how ‘bout that?”

After the show, Good Guy Grohl made sure to sign her cast, too. Watch him do just that, along with his dedication, in the videos at the bottom of the page.

In addition to demonstrating their general good-naturedness, the Foo Fighters also recently racked up yet another star guest to their cross-country Sonic Highways travels. Jewel was the latest to join a roster that already includes Jack Black, Stevie Nicks, Haim, Yes’ Jon Davison and more.

At their concert in Phoenix on Friday (Sept. 25), Jewel accompanied the Foos for an unrehearsed cover of Led Zeppelin’s “Whole Lotta Love.” As Grohl explained pre-performance, they were going to play “some nice thing that we thought would sound good,” but Jewel changed her mind last minute.

“She says to me, ‘I don’t want to do that,’” Grohl recounted. “She says, ‘I wanna do this.’” Then, they launched into an impressive rendition of “Whole Lotta Love,” which you can watch in the fan-made clip below.
