Happy Birthday to Don Henley, who turns 71 on Sunday (July 22nd)!!! Henley and the late Glenn Frey co-founded the Eagles in 1971, and are responsible for the band's best loved songs, including "Hotel California," "One Of These Nights," "Desperado," "Best Of My Love," "Life In The Fast Lane," "Tequila Sunrise," "Take It To The Limit," "New Kid In Town," "The Long Run," and many more. The Eagles -- featuring Deacon Frey and Vince Gill -- perform tonight and tomorrow (July 20th and 21st) at Boston's TD Garden.

In 2016, the Eagles were saluted with the prestigious Kennedy Center Honor. In 2015, Don Henley released his latest solo album, Cass County, which marked his highest charting solo set to date -- debuting on the Billboard 200 album charts at Number Three -- a full four spots higher than his last album, 2000's Inside Job. In addition to that, Cass County debuted at Number One on Billboard's Top Album Sales and Top Country Albums charts marking the first chart-topping album of Henley's solo career, selling more than 87,000 units in its first week of release. Cass County features collaborations with Mick Jagger, Stevie Nicks, Merle Haggard, Dolly Parton, Martina McBride, and Miranda Lambert, among others.

Since originally parting ways with the Eagles in 1980, Don Henley has scored eight Top 40 hits -- including the Top Tens: "Leather And Lace" - with Stevie Nicks (#6), "Dirty Laundry (#3), "The Boys Of Summer (#5), "All She Wants To Do Is Dance" (#9), and "The End Of The Innocence" (#8).

In April 2011, Henley was honored in Washington, D.C. at the 10th annual Grammys on The Hill for his advocacy on behalf of the music community. Henley was awarded the inaugural Recording Artists Coalition award.

Although the press has unsuccessfully tried to pigeonhole Cass County into being a "country" album, Henley maintains that it was conceived and recorded without any hangups as to where it would fit and who would be buying it: "There’s been a lot of discussion when they were trying to fit in what categories to put it in (laughs), y’know, for, like, iTunes. There’s been a lot of argument back and forth, ‘Well, is it a country album? Is it an Americana album? Is it a pop album -- what is it? And the fact is, it’s all those things. It’s just an American music album. I don’t like to put things in boxes."
