Good lord, I thought, look how old these people are. It was a few minutes before 62-year-old Bruce Springsteen and his now multigenerational E Street Band went onstage. The crowd was pouring in, waiting on line for a beer or a hot dog or an appallingly overpriced T-shirt.
I had seen older people at previous Springsteen concerts, of course -- going all the way back to my first, in 1984 in Toronto, when I scored a seat in the 14th row by taking advantage of a desperate scalper with excess inventory just before show time.
That was when I was 17, the age that another musical son of New Jersey, Frank Sinatra, famously singled out as "a very good year" -- the point where youth begins revving up into adulthood.
The average age of this crowd was well past 35, the last digits cataloged by Sinatra in the lyrics to "It Was a Very Good Year."
Until Monday night, I was usually able to convince myself that those people had been dragged to the concert by their children or grandchildren. But now they were everywhere, outnumbering the younger folk -- many of whom had clearly been dragged there by their parents or grandparents.
My seat was in the upper deck, next to a married couple from Orange County who had seen Springsteen in concert about 30 times. The best show, according to the wife, had been a stop on the "Darkness on the Edge of Town" tour at the Capitol Theatre in Passaic, N.J.
"I was pregnant out to here with my 33-year-old son," she recalled, indicating the sort of belly you wouldn't want to have pressed against the stage.
The woman was holding a bag that contained a new $40 T-shirt.
