This Sunday night, we'll find out how many of Beyoncé's 10 Grammy nominations get converted into trophies, whether MGMT are too weird for the Academy's voters, and whether Lady Gaga will start a fire onstage when music's biggest night is televised live from Los Angeles. Before we look ahead to who biz insiders think can walk off with the most hardware, let's look back at last year's ceremony's biggest winners, losers and memorable moments:
• Robert Plant & Alison Krauss, Lil Wayne and Coldplay scored the most Grammy Awards: Plant & Krauss grabbed five Grammys, including the night's biggest award, Album of the Year, for Raising Sand.
• Blink-182 reunited onstage to announce their return. "We used to play music together, and we decided to play music together once again," said Travis Barker.
• The altercation between Chris Brown and Rihanna nearly overshadowed the actual Grammy ceremony; the pair dropped out of their scheduled appearances after Brown assaulted then-girlfriend Rihanna following Clive Davis' annual pre-Grammy party.
• M.I.A. performed while practically giving birth. The rapper-singer took the stage with T.I., Jay-Z, Lil Wayne and Kanye West for an all-star rendition of "Swagga Like Us" while experiencing contractions; she had her son a few days later.
• Paul McCartney birthed a bromance with Dave Grohl. The pair teamed up on "I Saw Her Standing There" and palled around all weekend.
• Whitney Houston returned to the stage at Davis' pre-Grammy bash with a brief set that had Jennifer Hudson, Katy Perry and Jamie Foxx screaming for an encore.
