VIDEO : Johnny Depp, Gene Simmons Play Kiss Classics for Charity

Johnny Depp helped close a charity concert with heavy metal heroes, echoing the famous lyrics of Kiss classic "Rock and Roll All Night. The actor helped Gene Simmons, former Guns N' Roses guitarist Gilby Clarke and Mr. Big drummer Matt Starr perform two Kiss classics, "Deuce" and "Rock and Roll All Nite." No stranger to the six-string, Depp gamely kept pace with Clarke on "Deuce," swapping leads and throwing in some flourishes during the second verse. Depp was also one of a handful of guitarists to take the stage for closer, "Rock and Roll All Nite." Although the actor hung back for much of the performance, he stepped up to the mic and helped howl the track's famous refrain before unleashing the final descending riff.
