On Wednesday night, some of music's biggest stars came together for the 12-12-12 Concert for Sandy Relief at Madison Square Garden.
The concert – which included performances from Bruce Springsteen, Paul McCartney, Alicia Keys, Kanye West and more – raised money to benefit those affected by the superstorm in New York, New Jersey and Connecticut.
With an all-star lineup, every moment was better than the last, but here are our five favorites.
Mick Jagger's Still Got It
Maroon 5 wrote "Moves Like Jagger" for a reason! The 69-year-old Rolling Stones frontman proved on Wednesday night that age is just a number when he performed "You Got Me Rocking" and "Jumpin' Jack Flash."
New Jersey Pride
Two of New Jersey's proudest sons, Bon Jovi and Springsteen, shared the stage for Bon Jovi's "Who Says You Can't Go home." As they sang the lyrics together, Madison Square Garden witnessed a moment the Garden State won't ever forget.
Kanye West Wears a Kilt
Always fashion forward, West had social media buzzing on Wednesday night when he performed in a leather skirt – his outfit choice even spawned a parody Twitter account, Kanye's Skirt. But girlfriend Kim Kardashian chimed in to let fans know she was supportive of the rapper's ensemble. "Awwwwwwww I'm so excited right now!!!!! He looks so cute!!" she Tweeted.
Chris Martin's Semi-Solo Act
The Coldplay frontman left his band at home to perform "Viva La Vida," followed by "Us Against the World" on piano. When Michael Stipe joined the singer for a duet of R.E.M.'s "Losing My Religion," a new take on the 1991 hit was born.
Nirvana and The Beatles Weren't That Different After All
When news first broke that McCartney would lead a Nirvana reunion 18 years after Kurt Cobain took his own life, fans had little idea what to expect. But Sir Paul delivered! "We're gonna do the song we jammed now," McCartney said, introducing a new song with grunge-inspired vocals. Although Dave Grohl energized the set with his drumming, no one seemed to be having more fun than McCartney himself.
But not everyone was impressed by the performance. TMZ reports Cobain's widow Courtney Love was "not amused" by the reunion, saying "if John [Lennon] were alive it would be cool."
