Foo Fighters' frontman Dave Grohl gave his orthopedic surgeon the biggest thank you imaginable -- a solo on stage with the rock group. 

After paying tribute to Dr. Lew C. Schon for the work he did on Grohl's leg Sunday (July 19) at Fenway Park, the frontman brought his doctor on stage to perform a cover of The White Stripes' "Seven Nation Army." The doctor sang lead vocals, duetting with his patient and absolutely nailing it.

Foo Fighters have been able to continue their North American tour since Grohl broke his foot while performing in Sweden last month, which Grohl told the Associated Press has allowed for some of the band's best shows. The group continues the North American leg Aug. 12 following performances in Japan and South Korea.
