Crowd estimated at 700,000-800,000.

Producers of the Philadelphia Live 8 show feel like they pulled off "as close to perfect a show as you could have," according to Larry Magid, president of Electric Factory, a division of the Clear Channel Music Group. The show was held in front of the Philadelphia Museum of Art, produced by Electric Factory in conjunction with Live 8 executive producer Tim Sexton and Russell Simmons.

The Philadelphia Live 8 show drew a crowd estimated at between 700,000-800,000 to see a lineup of Black Eyed Peas, Bon Jovi, Dave Matthews Band, Def Leppard, Destiny's Child, Jay-Z, Toby Keith, Alicia Keys, Linkin Park, Maroon 5, Will Smith, Rob Thomas, Stevie Wonder and others. Magid, who also produced the Live Aid show at Philadelphia's Veterans Stadium 20 years ago, says the two events were comparable in how well they came off. He says the Live 8 show ran just 46 minutes over time-wise and despite the huge crowd there were only four arrests for minor incidents and no serious injuries outside of heat-related problems.

"You couldn't have asked for a better audience," Magid tells "I was proud to be a Philadelphean."

Two days after Live 8, Electric Factory produced the Elton John-headlined AIDS/HIV benefit, the Sunoco Philadelphia Freedom Concert, at the same location, drawing a crowd estimated at 300,000 Magid says. "We're all a little groggy right now," Magid admits. He estimates the Philadelphia Live 8 show alone cost between $5 million and $6 million to produce. "But that's just a drop in the bucket if these 10 shows are able to alter history, which I believe in my heart is happening right in front of us. Bob Geldof and I spoke earlier today and he said the attitude of the White House has changed dramatically. It looks like this whole thing is going to be successful."
