Foo Fighters front-man Dave Grohl played on the new Kristeen Young album, The Knife Shift. So, it was not surprising to see Grohl backing Young on the drums when she made her United States network debut on Craig Ferguson's Late Late Show earlier this week.
Grohl's Foo Fighters bandmate Pat Smear was also there playing guitar.
The group played Young's new song Pear of a Girl.
Dave Grohl played drums on every song on Young's album and contributed guitar to five tracks.
