KISS are gearing up for a farewell tour and the question on many people's minds has been: Will Ace Frehley join the band for the tour? (He wants to.) Well, this might be a step in the right direction: both KISS and Ace (as a solo artist) are currently on The KISS Kruise, and Ace performed with the band for the first time in 17 years. He joined Gene Simmons, Paul Stanley and the rest of the current KISS lineup during their acoustic set -- and '80s/'90s era member Bruce Kulick joined for it too -- and they played Ace's "New York Groove," KISS classics "Rock and Roll All Nite" and "Nothing To Lose," and a cover of The Rolling Stones' "2000 Man." Watch a video of all four songs below.

This follows Gene Simmons and Ace Frehley playing KISS songs together on tour in Australia earlier this year.

KISS' farewell tour is set to hit the NYC-area on March 22 at Nassau Coliseum and March 27 at MSG. Tickets for the whole tour go on sale Friday (11/2) at 10 AM local.
