The pianist, who turns 70 on April 12, will be joined by comedian Bill Cosby, saxophonist Joe Lovano, trumpeter Terence Blanchard, and saxophonist Wayne Shorter, Hanc**k's bandmate in Miles Davis' famed 1960s quintet, with more guests to be announced. The June 24 concert, "Herbie Hanc**k, Seven Decades: The Birthday Celebration," will benefit The Thelonious Monk Institute of Jazz.

"That will be a very exciting night perhaps one of the unique nights in the history of the festival with a lot of people coming just to salute Herbie," the festival's producer, George Wein, said Friday.

The concert will be followed by a festival first an old-time midnight jam session paying tribute to Hanc**k at the City Winery nightclub.

After lining up new sponsorship from medical technology company, CareFusion Corp., Wein has resurrected New York's flagship summer jazz festival, which he first launched in 1972. The festival was canceled last year after Japanese electronics firm JVC withdrew its sponsorship.
