The Eagles' Don Henley is currently in Nashville working on a country album, and now some of the details about the project are finally emerging, courtesy of Ronnie Dunn. Dunn recently mentioned recording a song for the album with Henley and Alison Krauss, and then he spilled the beans about that track to Nashville-based blogger Ashley Mann.

The tune Dunn sang on with Henley and Krauss was the Eagles' classic hit 'Seven Bridges Road.' Dunn said to walk into the studio that day was "terrifying" -- not only because he was meeting the Eagles' legendary drummer for the first time, but another of the country star's heroes was at the sound board: Stan Lynch from Tom Petty and the Heartbreakers. Dunn revealed, "He’s producing ... of course, we just take off and say, "Holy Cow! Stan Lynch!' 'Cause we used to watch that DVD -- all the guys in the band. It’s our go-to CD.'

When Dunn walked in the studio that day, he had no idea who else be'd be singing with, but he saw four microphones and found out that one of them was meant for Randy Travis. Henley tried to get him to sing on the tune as well, so they could have four-part harmony, but he was told by Travis' people that "he doesn’t sing harmony." As Dunn was listening to that story, he started laughing and said, "Don, I’m not sure if I sing harmony either!"

The 'Bleed Red' country star admitted that it was weird to have a legend like Henley coaching him through his harmony part. They ended up cutting the song live, and after he got home, Dunn got a text from Henley that read, "Man, you did a great job. Thanks for being so patient."

No other secrets from the album have been leaked just yet, but we do know that Henley is still in the recording process and that more country stars who may be involved will be named as the weeks go on. Dunn will be performing his new single, 'Bleed Red,' on the ACM Awards on Sunday night.
