The shocking news has dealt a painful blow to many of Frey's famous friends and fans, including Country singer Travis Tritt, who was a longtime friend of Frey.
"Glenn Frey and the music he created alone and with The Eagles have been such an inspiration to me," Tritt shared in a statement released to ET. "We first met at the video shoot for my version of 'Take It Easy' in 1993. He always went out of his way to acknowledge and encourage me ever since."
Tritt's cover of The Eagles' "Take It Easy" lead to the eventual reconciliation of the band, who reunited to appear in the song's music video in '93.
During the shoot, the previously-feuding bandmates ended up becoming friends once again, and reestablished The Eagles for the band's Hell Freezes Over Tour the following year. They continued touring through 2015, with the History of the Eagles Tour, which bowed in Bossier City, Louisiana on July 29, marking Frey’s last performance with the band.
"I'm a better person, better musician and a better songwriter having met him," Tritt concluded. "I still can't believe he is gone!"
