Adele to star at Grammys clouded by Houston death The Beach Boys and Britain's award-winning singer Adele will stage comeback performances Sunday at the Grammys, although the annual music awards will be clouded by the death of Whitney Houston. Paul McCartney, Coldplay and Bruce Springsteen are also among major acts to play in Los Angeles, where country legend Glen Campbell, suffering from Alzheimer's and on a farewell tour, will receive a lifetime achievement award. Arguably an even bigger comeback will be by the Beach Boys, who will perform on stage for the first time since announcing a 50th anniversary reunion tour and album. But the three-hour Grammys show risks being clouded by the death Saturday of Houston, found dead in her hotel room shortly before she was due to attend a traditional eve-of-Grammys party with her mentor, veteran producer Clive Davis. The singer, who was 48, had a string of number one hits in the 1980s and 90s including "I Will Always Love You," but later descended into a prolonged battle with drugs and drink. Grammys producer Ken Ehrlich said organizers were scrambling to include a tribute to Houston in the show involving Singer Jennifer Hudson, who was presented with her 2009 best R&B album Grammy by Houston. The tribute will be "respectful" while highlighting her stunning music, he told CNN, adding: "Knowing Whitney as I did ... she knew the importance of thrilling an audience, and that's what we still plan to do." Rapper West is nominated in the most categories at this year's Grammys -- the music industry's version of the Oscars -- while the Foo Fighters and Hawaiian crooner Bruno Mars were tied with Adele, with six nominations.
