More Acts Join NYC Katrina Benefit

The big Sept. 20 Madison Square Garden (search) benefit for Hurricane Katrina (search) victims just got bigger. So big, in fact, Radio City Music Hall will be open the same night for even more acts.

Among the performers at the Radio City show are Dave Matthews, Tom Waits, Joss Stone, Trey Anastasio, John Mayer, the Meters, and Galactic with the Mardi Gras Indians.

Simon and Garfunkel and Elvis Costello will join the previously announced artists at the Garden, who include Elton John, Bette Midler and Lenny Kravitz.

Legendary Fats Domino (search), who was evacuated from his New Orleans home after the hurricane, is scheduled to play at the Garden, along with fellow New Orleanians Irma Thomas, Kermit Ruffins, and the Neville Brothers.
