The Foo Fighters sang their own version of the White Stripes hit song 'Seven Nation Army' with a special guest, Dr. Lew C. Schon, who happens to be Dave Grohl's orthopedic surgeon during their Fenway Park show in Boston last Sunday.
The rock band did not miss out on thanking the man who was mainly contributed to the continuation of this year's sold out 'Throne' tour.
This year, lead singer Dave Grohl got into an accident and broke his leg while performing a show in Sweden. Dr. Lew C. Schon helped Grohl not just with surgery, but during the recovery period as well.
He was invited to come onstage, joining the band in their soulful rendition of 'Seven Nation Army'.
"Holy sh-t, that's actually my doctor. What a badass," were the few words that the rocker uttered as the whole crowd chanted "Lew" after Schon hugged the band members and pumped his fists.
Besides covering 'Seven Nation Army', the Foo Fighters also covered 'School's Out' by Alice Cooper. The track was played by Foo Fighters several times over for the past five years, however, this particular version of the song stood out with a surprise guest appearance by Godsmack vocalist Sully Erna.
After the band kicked off their North American tour with a star-studded 20th anniversary celebration held in Washington, D.C., the following showshad a couple of surprise guests, including the 'Bad Brains' members and the Red Hot Chili Peppers drummer, Chad Smith.
The Foo Fighters will be returning to North America after their trip to Japan and South Korea, to kick off a two-month show in Edmonton, Alberta on August 12, 2015. While the band has yet to confirm whether Dave Grohl's throne will still be used for the band's lineup shows, the singer said that he's starting to undergo rehab exercises.
"I'm starting to do a little bit of rehab exercise and the cast is off," Grohl said. "The swelling's down. The pain's gone. It's just a matter of getting those kick-drum muscles back, man. I can't f-kin' lose those. That's important to me. So I'm sitting here, moving it around, doing my exercise as we speak. So it's OK."
