Dubbed the “Buried Treasure” project, Jimmy Buffett says that he’s come across a collection of unreleased songs from the late 60’s and early 70’s that he plans to release soon:

The “Buried Treasure” project includes at least 20 original songs and perhaps some cover material Buffett recorded in Nashville between 1969 and 1973 with original producer Travis Turk.

“Two years ago they were going to sell the studio we were working at and owners said go through this and see if there’s anything you can use. He found 74 original songs I forgot I had written,” Buffett says. “It’s really, right back to the beginning stuff. … I’m going back and listening to myself during these times and it’s sparking stories. I don’t remember writing a lot of these songs but once I hear them stuff starts coming back. So I’m doing a narration through this material that we found. I’m going to do that as a project. They were tape recordings they were about to throw out. Some is cover stuff, but the original stuff there’s probably about 20 songs that I had forgotten I had written. … It’s something people might want to add to their collection.”

Although he’s uncertain when Buried Treasure might be released, Buffett says his work on the project should be done in the next couple months. “I’m working on that on the road.”

Meanwhile, he’s written some new songs, but says, “I’m at that point now where, do I really want to go into the studio and put out another album? I’ve got four or five songs new songs. Why don’t I just go in and record them and put them up on line? I’m not sure people really want to go get a whole album collection because of how iTunes has kind of taken the album away.”

Stay tuned, he says. “I’m kind of toying with how you go forward with new material. In the meantime I certainly know how to deal with this old material. They will want that as a collection.”

In an interview with USA Today that focuses mainly on releasing old material, Jimmy Buffett says he’s going to work on the tailgating prohibition at Jiffy Lube Live in Bristow, Virginia. Spokespeople for Jiffy Lube Live and owner Live Nation have said that they are cracking down on tailgating at the venue that is known for great pre-partying.

When told there wasn’t going to be partying in the parking lot, the singer said, “Who’s stupid idea was that? … I’m glad to hear that. I’ll get right on that. I believe I can take care of that. It must be some city thing, but it’s not me.”

The venue, formerly known as Nissan Pavilion “is one of the biggest tailgating places ever,” he says. “We got time, I can really get into that. … I’m going to fire a little shot to the Live Nation people.”

The Jiffy Lube Live concert will be held August 27th.

A Margaritaville-themed gaming area is coming to the Flamingo hotel, site of the Margaritaville Cafe, in Las Vegas.

The new gaming area will be adjacent to the Margaritaville restaurant in the former Steakhouse 46 location. Plans call for a 15,000-square-foot addition to the Flamingo’s casino with 22 table games and 220 slot machines.

“The Margaritaville brand eludes nothing but fun … that’s what gambling is about,” said Rick Mazer, regional president for five Caesars Entertainment properties in Las Vegas.

The $10 million addition is scheduled to open in October. Mazer said the companies have been partners since 2004 in the Margaritaville restaurant — a partnership he called “extremely successful” for both companies.

The master plan for the Margaritaville casino also includes the 5 O’Clock Somewhere Bar — named for a 2003 Buffett song “It’s Five O’Clock Somewhere” — with direct access to the Strip.

“We have this great restaurant experience. We intend to extend that experience into a themed (gaming area),” said John Cohlan, chief executive officer of Orlando-based Margaritaville Holdings.
