Monday marks the 30th anniversary of the globally televised Live Aid concerts for African famine relief, staged in London and in Philadelphia's long-gone JFK Stadium.

That sweltering day in Philly saw many iconic moments, such as Mick Jagger and Tina Turner's incendiary set, and the ill-fated Led Zeppelin reunion (ruined, according to Zep guitarist Jimmy Page, by drummer Phil Collins' incompetence and lack of preparation). Across the pond, U-2 did a career-making turn at London's Wembley Stadium.

But there were also many lesser-known, yet fascinating aspects to what will likely remain the most historic single-day entertainment event ever staged. Here are a few things you might not know.

From the moment such music-industry mahoffs as the late uber-promoter Bill Graham and Larry Magid, of Our Town's Electric Factory Concerts, gathered at City Hall to declare Philadelphia the host of Live Aid's American set, controversy took a seat on the podium.

At their June 11, 1985, news conference, concert organizers proudly unveiled an impressive preliminary roster of artists booked for JFK Stadium — Jagger, Eric Clapton, Santana, the Temptations, the Cars and Stevie Wonder.

Then the fireworks began.

Tommie St. Hill, today a lobbyist, then a reporter for The Philadelphia Tribune, pointed out that a concert being staged to help Africans had but two black acts — Wonder (ultimately a no-show) and the Temps.

All hell broke loose, with Live Aid honchos going on the defensive and accusing the media of trying to run down a noble project. The promoters ultimately added home girl Patti LaBelle, Ashford & Simpson, the Four Tops, Billy Ocean and the late Philly soul titan Teddy Pendergrass.

His lump-in-the-throat set was his first gig since the 1982 car crash that left him permanently wheelchair-bound.

Pretenders for real

For those lucky enough to have witnessed it, the single best Live Aid performance didn't happen at Live Aid.

In the days running up to the event, the performers booked every available professional-grade rehearsal studio in the area. Finding no vacancies, the Pretenders — who hadn't gigged in a year — decided to shake off the rust with a private, late-night Live Aid Eve set at the old Chestnut Cabaret, at 38th and Chestnut streets.

The band blasted through a greatest-hits show that included "Message of Love," "Back on the Chain Gang," "My City Was Gone" and "Brass in Pocket." It was a ferocious and indelible effort.
