Last Saturday, before McCartney plays, a Source Security worker tells me the papers will call the concert a disaster. He has dealt with a crowd constantly complaining that concession booths were blocking their view, and concertgoers were raging as they are pushed back and forth in the disorganized middle ground.
The worker says that only the grandstands have a clear view.
Later, when McCartney begins to play, I realize he's wrong about how this concert will be viewed.
Camera phones are raised like lighters, the sky is filled with rhythmically clapping hands, a reported 50,000 voices singing the same words.
They will only remember the show of a lifetime when they wait in line for tickets to KISS, a concert put on also by Power Promotions, with the same operational plans and same problems.
On this blazing hot sunny day are 400 Source Security guards, traveling on foot and by golf cart, roaming the grounds in yellow and black t-shirt bumblebee bands.
The guards keep the chaos under control, staff the gates, stop confrontations and deal with everything from fence jumpers to people speaking in tongues.
The guards don't fit the stereotype. Many are women, including 45-year-old KISS fan Nancy Singer. Chris Chapman, 17, is a lanky high school student who is too young to know why his last name might scare a Beatle.
The six-foot, two-inch, 250-pound team leader, sociology student Niko Williams, speaks like a born diplomat and uses his mind rather than his fists to solve problems.
From the gates opening in a tidal flood onto the green of the Common fields to the exit following the third encore---where the grass looks like an ashtray---the army of guards keeps the city safe.
This weekend they will try to do the same thing for KISS.
I'm guessing KISS fans may be a little less inclined to let it be.
