Dressed to the triple-sixes, the foursome signed autographs for fans before getting stuck in to the business of the day: A cameo spot on the locally shot TV series Millennium.
The band -- Paul Stanley, Peter Criss, Gene Simmons and Ace Frehley, in full makeup -- spent two days at the Rage nightclub playing their rock-star selves.
The episode -- which airs Oct. 30, the same day KISS launches its Psycho Circus tour at Dodger Stadium in Los Angeles -- follows character Frank Black (Lance Henriksen) as he searches for a serial killer on the set of a low-budget horror film on Halloween night.
Which explains yesterday's strange assembly of gutted and gored extras at the Plaza -- among them Canadian Shannon Tweed.
The former Playboy pinup turned actor, who is married to Gene Simmons, plays the bride of Frankenstein in the Millennium episode.
Celebrity photographer Paul Duchart says fans near the set, and those who gathered outside the Waterfront Centre Hotel, where the band was staying before jetting back to L.A. yesterday, were rewarded for their patience.
"They signed anything stuck in front of them. They were very classy about it."
Psycho Circus -- produced by Vancouver's Bruce Fairbairn -- entered the Canadian sales charts at No. 1 when it was released Sept. 22. KISS has sold 80 million records to date.
