There were many, many performers on Wednesday's "Celebrating America" inauguration event, including Foo Fighters.
Foo Fighters frontman Dave Grohl started off the performance thanking "teachers everywhere," including his mother Virginia.
Grohl dedicated the song to "all of our unshakable teachers that continue to enlighten our nation’s kids every day."
The band began their performance of "Times Like These" slowly, with just Dave's vocals and the organ before the full band kicked in.
