Brace yourself, Philly: "The Boss" plays for hours

• "The Boss" is famous for putting on marathon shows spanning three to four hours and encompassing more than 30 songs.

Driving the news: Springsteen and the E Street Band are playing a second show Friday at 7:30pm.

• The concerts are make-up dates after Springsteen canceled last year's Philly shows because of illness.

The intrigue: Springsteen played his second-longest show (4 hours, 4 minutes) in Philadelphia in September 2016, per concert statistic tracker MyBossTime.

• It was a minute shy of a concert he put on in Helsinki, Finland, years before.

What they're saying: Grammy-winning musician Paul McCartney told People that few artists performed that long before Springsteen popularized it.

• "I've told him … 'It's your fault,'" McCartney said. "We used to do a half hour. That was The Beatles' thing – half an hour, and we got paid for it."

If you go: Tickets are still available for both shows.
