Jimmy Buffett is lending his voice to a Mark Twain tribute album that is being put together by the Mark Twain Museum in Hannibal, Missouri:

The country-flavored CD is still a work in progress. Some of the audio is still scratchy around the edges. Carl Jackson’s voice fills in for Jimmy Buffett’s throughout the current product as he waits for Buffett, a late contributor, to finish recording his spoken-word turn as Twain’s ragamuffin hero Huckleberry Finn.

Clint Eastwood plays the voice of Twain in the dialog with Buffett that will buffer between the musical numbers on the album. Other artists lending their voice and musical talents include Brad Paisley, EmmyLou Harris, Vince Gill, former Shenandoah frontman Marty Raybon, Doyle Lawson and Quicksilver, and more.

Mark Twain has been very influential on the music and writings of Jimmy, most notably on the songs That’s What Living Is To Me and Take Another Road.

The museum hopes to release the album in time for the holidays.

While Jimmy’s not doing any public shows this month, he does have three private shows lined up this weekend.

On Saturday he’ll perform at the Andy Roddick Charity Gala in Austin, Texas. Then on Sunday he’ll head to New Orleans for the New Orleans Artists Against Hunger & Homelessness gala. And on Monday Buffett will head back to Texas to play a private show for invited American Express cardholders at the Toyota Center in Houston.

He said that he hopes to provide more details in the coming days.
