This December, southern rockers the Marshall Tucker Band will be hitting the seas as they co-headline the annual Rock Legends Cruise, benefiting the Native American Heritage Association (NAHA). The band will share headlining duties with the legendary ZZ Top, as they set sail on the Royal Caribbean Cruise.

"That boat is going to be rockin' for three or four days," MTB's lead vocalist and founding member, Doug Gray, tells Ultimate Classic Rock. "It's going to be a great time. We've all got three shows each in different locations on the boat, plus I get a three and a half hour jam session. It is going to be one hell of a party on the Atlantic!"

The ship will depart from Ft. Lauderdale on Dec. 1, returning back from the four-day Bahamian cruise on Dec. 4. Joining the Marshall Tucker Band and ZZ Top on this year's cruise will be George Thorogood & The Destroyers, John Kay & Steppenwolf, Dickey Best & Great Southern, Foghat, Molly Hatchet, Johnny Winter, The Edgar Winter Band, and The Outlaws, and many others.

The ship is scheduled to head to stops in Bahamian cities Coco Cay and Nassau, all while passengers are entertained with the cruise's main attraction -- the live performances.

The unprecedented cruise will benefit Native American Heritage Association’s mission to provide emergency assistance and self-help programs to the Sioux Native Americans living on reservations in South Dakota.
