Glenn Frey, guitarist and founding member of The Eagles, has died at the age of 67, according to a statement posted on the band's website.
"Glenn fought a courageous battle for the past several weeks but, sadly, succumbed to complications from Rheumatoid Arthritis, Acute Ulcerative Colitis and Pneumonia," the statement read.
The band included the lyrics for "It's Your World Now" from their 2007 album Long Road Out of Eden. The song was co-written by Frey and frequent Eagles' collaborator Jack Tempchin.
Frey founded the Eagles in 1971 along with Don Henley, Bernie Leadon and Randy Meisner. They began as Linda Ronstadt's touring band before releasing their eponymous debut album in 1972. Its first single was "Take It Easy." Over the next 45 years, the band went on to sell over 150 million albums worldwide. Frey and Henley have always represented the group's nucleus, and were the only two members remaning from the original four founders.
"He was like a brother to me; we were family, and like most families, there was some dysfunction," Henley wrote in a statement. "But the bond we forged 45 years ago was never broken, even in the 14 years that the Eagles were dissolved. We were two young men who made the pilgrimmage to Los Angeles with the same dream: to make our mark in the music industry—and with perserverence, a deep love of music, our alliance with other great musicians and our manager, Irving Azoff, we built something that lasted longer than anyone could have dreamed."
