The alum, Matthew G. Hegerty ’84 said he received many replies and has purchased a set of tickets.

He said he never expected the tickets to be difficult to obtain.

“I don’t recall any year where there was demand,” Hegerty said.

Hegerty’s tickets will be going to his co-workers who he said were very excited to hear Bono speak at Harvard. But he predicts many other fans won’t be so lucky.

“I imagine there will be a lot of people outside of Johnson Gate on June 6,” Hegerty said.

The increased security efforts outside Johnston Gate won’t influence what goes on inside, according to the Harvard News Office.

“The Class Day process, as far as what the seniors and guests are allowed to do, will be unchanged,” Rollins said. “The concern is going to be limiting access.”
