Steve Jones of Sex Pistols has a show on 95.5 KLOS, an LA radio station. Jones is currently out on the road promoting his new book, so Foo Fighters' Dave Grohl and Taylor Hawkins took over the show. Instead of making it into their own thing, Grohl takes on the position of Jones, and does a friggin' dead on impersonation of him throughout his "interview" with Hawkins.
Of course, the interview is about Foo Fighters.
