THE WHO AT CINCINNATI'S RIVERFRONT COLISEUM IN 1979

Weeks before Christmas in 1979, 11 people died after a crowd surge of those attempting to get into a concert by The Who scheduled to be held at this major venue in Cincinnati.

First come, first serve festival seating was blamed for the tragedy as concert goers rushed to try and get inside before all the doors had been opened.

According to Cincinnati.com, The Who frontman Roger Daltrey quietly visited the Finneytown memorial site in 2018 to pay tribute to the victims.

"Because there's always a certain amount, 'If I hadn't been doing this, it wouldn't have happened,' you know," Daltrey was quoted as saying. "That's just human nature. That's what we carry with us."

The group had planned to return to the community for a gig in April 2020 as part of their "Moving On!" Tour, but it was postponed due to the coronavirus pandemic.

Pete Townshend of The Who reportedly talked to Pearl Jam lead singer Eddie Vedder to offer him advice based on The Who's similar tragedy.

"There I was in a fetal position, basically, and Pete said, 'You can handle this,'" Vedder said. "And I said, 'I can't.' I was like, 'I don't know, Pete, I don't think I can. I'm losing it.' And he said, 'No, you can handle this."
