Legend Don Henley is set to host his own 70th birthday bash in concert July 22 at the American Airlines Center in Dallas. Henley is expecting about 20,000 guests.

The concert is a benefit efforts to preserve Caddo Lake. Henley has always had a passion for the lake, which is near his hometown of Linden, Texas.

The money will go toward the Caddo Lake Institute, a nonprofit Henley founded in the '90s to aid in his fight to keep developers away from the lake on the northern Texas-Louisiana border, where he keeps a home.

Henley will perform songs from his solo career and from his career with the Eagles, and he'll be joined by two of his former bandmates, Timothy B. Schmit and Joe Walsh, along with Stevie Nicks, Patty Smyth, and other surprise acts.

Tickets are available here.
