CMT Presents Jimmy Buffett & Friends Live From the Gulf Coast, a 90-minute live concert special, will air July 11 at 7 p.m. ET/PT on CMT. The event, originally planned for Thursday (July 1) on the beach in Gulf Shores, Ala., was rescheduled for July 11 because of concerns about surf conditions on the beach. Although Hurricane Alex pounded the coasts of Mexico and Texas, the effect of the storm is expected to increase water inundation at the beach in Gulf Shores. Thursday's concert was postponed because heightened surf conditions could potentially undermine the stability of a stage constructed on the sand. Buffett's special guests for the July 11 concert have not been announced. Kenny Chesney and Zac Brown were among those announced to appear at Thursday's show. CMT Presents Jimmy Buffett & Friends Live From the Gulf Coast will air live and commercial-free on CMT and will be streamed on CMT.com. The performances will be simulcast live on Radio Margaritaville, available on Sirius Satellite Radio and XM Satellite Radio.
