“We were two young men who made the pilgrimage to Los Angeles with the same dream: to make our mark in the music industry,” the statement said in part. “It will be very strange going forward in a world without him in it. But, I will be grateful, every day, that he was in my life. Rest in peace, my brother. You did what you set out to do, and then some.”

When the Eagles broke up in 1980, Frey launched a successful solo-career recording hits like “You Belong to the City,” and “The Heat Is On.”

Henley and Frey first met at West Hollywood’s Troubadour.

The Eagles reunited in 1994 for the album “Hell Freezes Over,” which was a mix of live and studio tracks.

They have toured off and on since then were inducted into the Rock and Roll Hall of Fame in 1998.

Frey passed away in New York City Monday.
