LOS ANGELES (CNN) -- Adele thanked her doctors "who brought my voice back" as she accepted one of six Grammy awards Sunday night.
The 23-year-old British songstress Adele, who underwent surgery for "recurrent vocal cord hemorrhage" in November, sang "Rolling In The Deep," ending speculation about her recovery. Adele enjoyed a loud and long standing ovation from the packed Staples Centers audience after her strong delivery.
Just minutes earlier, she and songwriting partner Paul Epworth won the song of the year Grammy for their collaboration on the song.
The first Grammy handed out in the live telecast was given to Adele for best pop solo performance, which she earned with her song "Someone Like You."
Adele won two Grammys in the pre-telecast ceremony for best short form music video for "Rolling In The Deep" and best pop vocal album for "21."
Chris Brown's career rehabilitation from his arrest for the beating of his then-girlfriend Rihanna just before the 2009 Grammys took another step forward with a Grammy win and a performance Sunday.
"We got one!" the 22-year-old Brown said during a short acceptance speech after winning a Grammy for best R&B album.
Rihanna was given her turn to perform during the same hour, collaborating with Cold Play on stage.
The Beach Boys, celebrating their 50th anniversary as a group, performed together publicly for the first time in two decades, joined on stage by Foster The People and Maroon 5.
"It was a good vibration," Beach Boy Mike Love said backstage. "It was fun, fun, fun, too."
"It's a big event in our lives," Brian Wilson said. "What more can you ask for?"
One-time Beach Boy Glen Campbell watched from near the stage, and later performed in his own Grammys tribute.
Campbell, 75, launched his "Goodbye Tour" last year after revealing he had been diagnosed with Alzheimer's disease.
Campbell was joined by current Grammy nominees Blake Shelton and The Band Perry for a live performance as part of a tribute to Campbell, a five-time Grammy winner.
"Thank y'all so much," Campbell said, after a rousing rendition of "Rhinestone Cowboy" during which he showed no signed of disability.
Campbell was presented a Grammy lifetime achievement award in a ceremony earlier.
Tributes to Whitney Houston, who died suddenly Saturday, were frequent in the telecast, including a replay of her memorable Grammy performance of "I Will Always Love You."
Host LL Cool J said a prayer for Houston in the first minutes for the 54th annual awards show, which is being telecast from the Staples Center in Los Angeles.
Alicia Keyes and Bonnie Raitt sang a musical tribute to legendary singer Etta James, who died last month.
American folk indie favorite Bon Iver was awarded the best new artist Grammy.
"When I started to make songs, I did it for the inherent reward of making songs, so I'm a little uncomfortable up here," singer-songwriter Justin Vernon said as he accepted.
The Grammy for best rock performance went to Foo Fighters for "Walk." It was the fifth Grammy given the group Sunday.
Lady Antebellum won the Grammy for best country album for "Own The Night."
Jay-Z and Kanye West won for best rap performance for their collaboration "Otis." It was the fourth Grammy won by West Sunday.
