Dave Grohl has extended his record for most appearances on SNL when Foo Fighters were the musical guest over the weekend.
They brought back Christopher Walken for a make good on his previous introduction. In 2003, they told Walken that the emphasis was on "Fighters", and he introduced them accordingly. He did a little better this time.
They came back and played "The Glass" with H.E.R. who has also recorded her own version of the Foo Fighters song.
