The show will also host a string of other New Orleans legends including the Neville Brothers, Clarence "Frogman" Henry, Dave Bartholomew, Irma Thomas and Kermit Ruffins.
But Rod Stewart has pulled out because he is recovering from shoulder surgery, US magazine Billboard reported.
The shows will raise money for charities including the Bush Clinton Katrina Fund, Habitat for Humanity and MusiCares Hurricane Relief Fund.
Bono, Maroon 5, Alicia Keys and Brian Wilson are among the stars who have already performed at a string of benefit concerts to help the fundraising effort.
Several other high-profile benefit concerts are being planned, including a night of jazz on Saturday at the Lincoln Center in New York featuring Wynton Marsalis, Bill Cosby, Paul Simon and James Taylor.
Also on Saturday, urban stars such as Nelly, Twista and TI will perform in Atlanta for the Heal The Hood foundation.
From Sunday, rock band Dashboard Confessional will begin three nights of benefit gigs in Toronto, Chicago and Sayreville, New Jersey, with the hope of raising $500,000 (£274,000).
