The 2014 Grammy Awards were full of powerhouse performances, but the most moving, by far, belonged to Macklemore & Ryan Lewis with Mary Lambert.
Their performance lit up L.A.'s Staples Center, and was made all the more stirring with Queen Latifah officiated 33 marriages, many of them same-sex.
As if that wasn't enough, Madonna, a champion of equality for decades, joined Macklemore, Ryan and Mary on their gay marriage anthem "Same Love."
Watch the powerful effort from the 2014 Grammy Awards winners, who received a thunderous ovation from the capacity crowd, for yourself below ...
Toward the end of the duo's hit, Madonna joined Mary Lambert to conclude the song with a mash-up of the “Same Love” chorus and “Open Your Heart.”
Queen Latifah joined the singers in unison, along with a gospel choir and horn aficionado Trombone Shorty amidst a backdrop of stained glass windows.
After introducing the performance, Latifah returned to the stage at the end to formally officiate 34 gay marriages in an incredibly emotional moment.
Thirty-four smiling couples exchanged rings in front of the arena audience, and 40 million viewers, as the ordained minister pronounced them married.
That's a hard act to tough ... even if you're Beyonce and Jay-Z and "Drunk in Love." What did you think of the performance? Tell us in the comments!
