Aerosmith guitarist Joe Perry remained stable in a New York hospital Monday after he collapsed onstage during a concert Sunday night with his superstar side band, the Hollywood Vampires.
The band confirmed that it was canceling its scheduled appearance Monday night on "The Late Show With Stephen Colbert," whose producers said Blink-182 would step in.
But Alice Cooper, the Vampires' lead singer, announced that the band would resume its nationwide tour Tuesday in Kettering, Ohio.
Whether or when Perry will be with them isn't known. Tom Hamilton, Aerosmith's bassist, tweeted Monday that Perry "seems to be better than we all first feared."
In addition to Cooper and Johnny Depp, the Vampires are often joined by a rotating cast of music superstars. Sunday night's show at The Amphitheater at Coney Island included Guns N' Roses and Velvet Revolver drummer Matt Sorum and Stone Temple Pilots guitarist Robert DeLeo.
Audience video of Sunday night's show, verified by NBC News, showed Perry, 65, sitting down on the front of the drum platform, then standing up and stumbling stage right behind a stack of speakers.
Kevin Phalon, an audience member, told NBC News that Perry collapsed during the second song of the band's set.
"After that, you could see a whole bunch of backstage people run off to the left side of the stage," Phalon said.
