Watch Ace Frehley Perform ‘New York Groove’ With the Roots

Last night found Ace Frehley back in New York City -- and, yes, back in the groove. Sitting in with the Roots on 'The Tonight Show Starring Jimmy Fallon,' the ex-Kiss guitarist tore into a funky version of his signature 1978 solo hit 'New York Groove' during a pre-show performance captured in the video above.

Frehley appeared in advance of the new solo effort 'Space Invader,' due next week via eOne Music. Featured are 11 originals plus a cover of the Steve Miller Band's 'The Joker,' the latter of which premiered exclusively on Ultimate Classic Rock.

There's a connection, in fact, between 'The Joker' and 'New York Groove' -- which was originally done by Hello prior to its inclusion on Frehley's self-titled solo debut.

"I was a little resistant when it first came up," Frehley has said, "but then I thought back to my 1978 solo record, when [Kiss producer] Eddie Kramer's assistant said to me, 'Why don't you try this song?' And it was 'New York Groove.' At first I said, 'I don't want to do that,' and it turned out to be my biggest hit. So maybe history can repeat itself."
