The enduring success of the Eagles means that Don Henley doesn't need to work unless he wants to. And when that time comes, it's hard to get him to stop. In a new interview, he discussed his upcoming projects that will keep him busy for the next few years, which includes a new solo album and autobiography.

Speaking to Andre Gardner of WMGK in Philadelphia, Henley disclosed that the record, 'Cass County' will be released in May. Named after the Texas county where he was born, Henley said the album "leans towards country. Some of it's traditional country, some of it is what you might call alt-country, and I've got a lot of interesting guest vocalists and musicians on there with me. I made a lot of the album in Nashville. Some of it was recorded here in Dallas and some of it was recorded in Southern California. I'm pretty pleased with it."

He and collaborator Stan Lynch (the original drummer from Tom Petty and the Heartbreakers) have been working on the album for three years. They about 16 songs completed with two more to be finished before figuring out which ones to include on the finished product.

There are also plans in the works for an upcoming Eagles tour. According to Henley, the show will focus on the 40-year history of the band, which will bring one former member back into the fold. While he would not disclose the name of the member, he admitted that it would not be Don Felder, who had a public and acrimonious split with the band in 2001.

Henley also acknowledged that he is writing his memoirs. "I'm actually working on it now," he said. "But it will be a few years before we get to that...I don't want to write a trashy tell-all...I think you can tell the truth and not get too salacious or prurient or tacky."

However, in front of Henley right now is the two-part documentary, 'The History of the Eagles,' that will debut on Showtime later this month. Henley admits that it was difficult to see his life reflected back at him on the big screen.

"We were always a pretty private band," he continued. We didn't allow a lot of access to our little entourage there. Partly, of course, because of our behavior." However, they did have their own film cameras capturing the backstage actions, some of which made it into the documentary, causing Henley to sardonically add, "I've got a lot of explaining to do to my kids."
