Downsview Park has been cleared and the Rolling Stones' performance is just a memory, but fans and organizers alike are "satisfied" Wednesday's night's SARS benefit concert went off without a hitch.

Two hours after the music had faded away, all 450,000 concertgoers were off the site, with police reporting few problems during the mass exit. And other than the massive load of garbage left over after the show, fans wreaked little havoc. About 120 workers were charged with the task Thursday of cleaning up the sea of paper, empty bottles, blankets and other garbage.

It was a "remarkably well behaved crowd," said police Chief Julian Fantino, and there was little need for the 1,300 officers on hand to control the crowds as they left. In all, police said there were 15 arrests, mostly for assaults and drunkenness.

"There's no damage and I think the city really did a phenomenal job this year," said Gerrit de Boer, whose furniture store bordering Downsview was badly flooded after the pope's visit last summer.

"This was a phenomenal concert. ... We see how we as Torontonians have really bonded together," de Boer told CTV's Canada AM.

Despite the "worst case scenarios" organizers had to be prepared for with a crowd of such magnitude, there were no major injuries or incidents.

About 465 people were treated at an on-site field hospital, mostly for heat exhaustion, reported CTV's Janis Mackey Frayer. As well, another 1,800 cases were treated in the crowd.

The Stones burst on stage Wednesday night with an energetic performance of Start Me Up and concluded the show with Jumpin' Jack Flash. The headliners followed a lineup of 14 acts, assembled to give Toronto a psychological and economic boost after its battle with SARS this spring.

Video images were beamed around the world from Toronto's Downsview Park, although the promised "live" coverage disappointed fans hoping to get an armchair view of the show. While CBC and MuchMusic both boasted live two-hour specials, they weren't granted the rights to air the concert's finale. Instead, much of the coverage was comprised of replays and snippets of the performances.

But the hordes of screaming fans at Downsview were treated to the real deal. "I'll tell you this is the biggest party in Toronto history," said lead singer Mick Jagger, from the concert stage. "Toronto's back and it's booming."

Jagger thanked Toronto's health-care workers -- several thousand of whom received free tickets to the concert in appreciation for their tireless work during the SARS crisis.

The Stones, who call Toronto their second home and often rehearse here, interrupted the European leg of their world tour for the benefit. At a news conference, guitarist Keith Richard grinned and growled that the band flew to the city to help out "because we love you."

Canadian performers like Sass Jordan were visibly moved by the sheer size of the crowd, and the enthusiastic response.

The show got underway at 12 p.m. ET with the arrival of three Canadian military parachutists and a rendition of the national anthem by Jann Arden. Next up were the inimitable blues-stylings of Dan Aykroyd and Jim Belushi. Sam Roberts, Blue Rodeo and Kathleen Edwards worked the afternoon crowd.

In the evening, world-class acts including AC/DC, Rush and the Guess Who got the audience primed for the Stones.

The only performer to experience a problem was teen act Justin Timberlake, who was pelted with water bottles and booed during his performance. But he took the incident in stride. "I think that's natural," he told reporters. "If I came to see AC/DC I probably wouldn't want to see me either."

Timberlake later joined the Stones for a rousing version of Miss You - interspersed with a sample from Timberlake's recent hit, Cry Me a River.

Some proceeds from the event will go to hospitality and health care workers hit by the SARS crisis.

Beyond the cash infusion is a good break on publicity. Toronto made for frightening headlines in recent months, as the only North American hotspot in this year's international SARS outbreak.

Tourists have stayed away in droves, frightened by reports of hundreds of cases of the disease and 42 deaths. The negative publicity is estimated to have cost the once-booming tourism and hospitality industry $2 billion in lost revenue.
