But the producers behind the program, which is to be broadcast live by CBS at 8 p.m., are hoping that the biggest show-stopper of the night will be a much more solemn event: an on-air wedding of 34 couples — gay, straight, old, young, of many races and many colors. The ceremony will be part of the hip-hop duo Macklemore & Ryan Lewis’s performance of their Grammy-nominated song “Same Love,” which became a marriage-equality anthem last year just as that issue was drawing intense national attention.
Mr. Lewis, the group’s producer, said that the weddings “will be in our minds the ultimate statement of equality, that all the couples are entitled to the same exact thing.”
The segment follows what the Grammy organizers said was the show’s long history of addressing timely social issues through music, like Elton John’s duet in 2001 with Eminem, who was then widely criticized as homophobic.
“We’re serious about this,” said Ken Ehrlich, the longtime producer of the Grammys.
The couples involved were forced to sign confidentiality agreements and not tell their families, according to the paper.
