Watch Sam Smith, Mary J. Blige Perform Emphatic 'Stay With Me' at Grammys

The duo enlist orchestra and choir to belt out Grammy-winning single

Sam Smith, already having a big Grammy night with four wins, enlisted Mary J. Blige for a glorious rendition of his hit "Stay With Me." Accented by the warm glow of lamps all over the stage, an orchestra and a choir, Smith and Blige gave some of the night's best vocals on the British pop-soul singer's Grammy-winning single. 

Smith and his debut album In the Lonely Hour were nominated for six awards, including Best New Artist and Album of the Year. In his Rolling Stone cover story, the singer noted that he hoped to lose to Beyonce in the Album of the Year category. "She deserves it way more than I do," said the superfan. "I'd be embarrassed if I got it over her. If I got it, I'd give it to her."

Beck ended up winning Album of the Year for Morning Phase, but Smith dominated the awards, winning four trophies, including Record of the Year and Song of the Year. 

Smith contributed songwriting credits on several tracks for Blige's last album, The London Sessions, including her single "Therapy." Over the course of her career, Blige has won nine trophies and has been honored with 31 nominations. 

Recently, Smith has been embroiled with some legal issues over his hit single "Stay With Me" against classic rocker Tom Petty. The publishers for Petty's hit "I Won't Back Down" claimed that the song's melody had been ripped for Smith's tune. The pair reached a settlement quietly, with Smith agreeing to give co-writing credit to Petty and Jeff Lynne. "I have never had any hard feelings toward Sam," Petty wrote. A musical accident no more no less. I wish Sam all the best for his ongoing career."

On February 25th, Smith will see if any of his five Brit Awards nominations come to fruition. The singer ventures out on a world tour this spring.
