John Lennon's Sons Performing Together For The First Time

According to FoxNews.com, the Lennon brother's LIVE performance will take place at the United Nations MDG Awards on Feb. 26., in the General Assembly Hall.

This event will pay tribute to individuals, organizations, and nations working to implement the body's Millennium Development Goals.

Other performers will include Jon Bon Jovi, Richie Sambora, Macy Gray, and hip hop singer Akon.

Julian Lennon, 45, had blogged on his Myspace about the up-coming event, but only confirmed that he would be performing and did not mention if his 33-year-old half-brother, Sean, would be included.

MDG Awards organizer, Sacha Stone, did not confirm any details of the show.

In 2007, the brothers had reconciled after a nearly decade long estrangement.

Sean's mother is the former Beatle's widow, Yoko Ono, while Julian's mom is Cynthia Lennon, who was John Lennon's first wife.
