BSB's Howie Remembers Sister With Benefit Concert

Backstreet Boy Howie Dorough and his sisters Angie Haring and Pollyanna Dorough are organizing "Lupus 2000," a benefit concert in honor of their late sister.

There's no firm lineup yet, but Christina Aguilera, fellow Backstreet Boy A.J. McLean, Sting, Deborah Cox, Leann Rimes, Jordan Knight, and Deborah Gibson have all been approached. British pop rocker Seal, who suffers from Lupus, has also been asked to perform for the benefit.

Howie D. and his sisters plan to perform a new song called "Fly To Heaven" in memory of their late sister.

The show is scheduled to take place on June 25 at Universal Studios in Orlando.

Howie's sister Caroline died in 1998 of Lupus, a chronic auto-immune disorder that affects the skin, joints, and internal organs (see "Backstreet's Howie Addresses Loss Of His Sister").
