According to TMZ,
Frey had been battling intestinal issues for months and had surgery in November. We’re told in the last few days his condition took a turn for the worse.
Glenn was a key player in the band … co-writing and singing lead vocals on several Eagles hits, including “Take It Easy,” “Tequila Sunrise,” “Lyin’ Eyes,” and “Heartache Tonight,” to name a few. He also co-wrote “Hotel California” and “Desperado” with Don Henley and took home 6 Grammys with the band.
After the Eagles’ 1980 breakup, Glenn launched a successful solo career recording numerous hits,most notably “The Heat Is On,” which appeared on the soundtrack to the Eddie Murphy blockbuster “Beverly Hills Cop.”
He reunited with the Eagles in ’94 for their monster Hell Freezes Over tour and recorded music till the end, releasing what would be his fifth and final solo LP, “After Hours,” in 2012.
The Rock and Roll Hall of Famer had been fighting intestinal issues for awhile but his condition relapsed before the holidays, forcing the Eagles to pull out of their Kennedy Center Honors appearance in December. At the time, the band said he needed major surgery that would require a lengthy recovery, but it appears he was never able to bounce back.
Glenn was 67. RIP.
