Glenn Frey, Don Felder (Brad Elterman/FilmMagic)Ex-Eagles guitarist Don Felder may not have been on the best of terms with Glenn Frey, but he had many kind words to share about his former band mate in a tribute he penned to Frey, who died Monday of complications from arthritis, ulcerative colitis and pneumonia.

“Glenn’s passing was so unexpected and has left me with a very heavy heart filled with sorrow,” writes Felder, who joined the Eagles in 1974, but was fired from the group in 2001 and subsequently launched an unlawful termination lawsuit against the band. “He was so young and still full of amazing genius.”

Felder calls Frey “an extremely talented songwriter, arranger, leader, singer, guitarist,” while noting that he could “create ‘MAGIC’ on the spot.” He adds that Glenn’s “visions and insights into songs and lyrics have become legendary and will echo throughout time on this earth for decades to come.”

Don points out that it was Frey who invited him to join the Eagles, and says it was “a gift of a lifetime to have spent so many years working side by side with him.”

Regarding their sometimes-contentious relationship, Felder explains, “At times it felt like we were brothers and at other times, like brothers, we disagreed. Despite our struggles and difficult moments together we managed to create some magical songs, recordings and live show[s].”

The guitarist says he has “many wonderful memories” of the years he and Frey spent in the Eagles, noting that those times were “filled with laughter, song, parties, hugs and brotherly bonds.”

Felder describes Glenn as “the James Dean of the band” and “the leader that we all looked to for direction. He also laments that “we were never able to address the issues that came between us and talk them through,” maintaining that “[s]adly now we will never get the chance.”

Bringing his homage to a close, Felder writes, “The planet has lost a great man and a wonderful musician today. None will ever be able to take his place.”
