The Jackson 5 will make their comeback performance on New Year's Eve with "the biggest party ever seen".
The legendary pop siblings - including Michael - will be flown in by helicopter to perform a selection of their greatest hits at Atlanta's Studio 72 Club to celebrate their sister Janet's engagement to music producer Jermaine Dupri.
Dupri, who is organising the event, told US radio station V-103: "It's the Jackson 5 party. I swear to you it's going to be the biggest party ever seen. At midnight I'm going to empty the whole club and put everyone in the parking lot and I'm going to light the lot up with a fireworks show."
Last month, it was revealed brothers Michael, Jermaine, Marlon, Tito and Jackie would embark on a world tour in 2008.
Jermaine said: "Michael will be involved. We want to tour. We want to touch the lives of everybody who's bought our records and supported us."
The Jackson 5 enjoyed huge success in the 70s with hits like 'ABC', 'I'll Be There' and 'Blame It On The Boogie'.
Their last record was '2300 Jackson Street' in 1989. They have not performed live together since their Victory World Tour in 1984.
