Stone Temple Pilots frontman Scott Weiland got naked for a Toronto audience of 5,500, at a free, outdoor concert Tuesday night.

The singer ended the hour-long show by tying a Canadian flag into a sarong, with the maple leaf sitting squarely on his backside, and stripping off his clothes underneath, save for his calf-high black socks.

As he turned to walk off stage, bassist Robert DeLeo tugged at the fabric, finally succeeding in ripping it from his body. He left the stage strategically covering his privates but exposing his well-toned behind, which was magnified on the giant video screen.

The rock band played the thirteen-song set in the parking lot of the city's MuchMusic video station, following an interview and three-song performance that was broadcast live in North America. The full concert that followed will not air until the fall, due to contractual reasons.

Fans started lining Queen Street West at four in the afternoon to hear STP's forty-minute sound check. By the time Weiland, bassist Robert DeLeo, guitarist Dean DeLeo and drummer Eric Kretz hit the stage just before 9 p.m., 1,500 wristband recipients filled the enclosed parking lot, with another 4,000 filling the shutdown street. Others hung out of office windows and stood on rooftops.

Bare-chested for the majority of the show, except for elbow-length gloves in both black latex and red velvet, Weiland writhed around onstage like a demented modern dancer. Toward the end of the concert, he climbed into the crowd on a couple of occasions and perched atop the wire fence facing the main street throng.

The set consisted of "Crackerman," "Regeneration," "Days of the Week," "Vasoline," "Big Empty," "Piece o' Pie," acoustic renditions of "Sour Girl," "Wonderful" and "Interstate Love Song," and then back-to-band versions of "Trippin' on a Hole in a Paper Heart," "Plush," "Down" and "Sex Type Thing."
