The Madison Square Garden concert will air live as pay-per-view telecast that will cost $19.95. Viewers should contact their cable or satellite provider to order the program.

Veteran television producer Ken Ehrlich--who has produced 25 Grammy Award telecasts, created and produced the "MTV Movie Awards" and "Divas," as well as numerous other specials, concerts and live events--will oversee the live broadcast.

All money raised from ticket sales, pay-per-view orders and sponsorships will go toward the relief and rebuilding efforts in the Gulf Coast region, according to organizers.
