The Eagles were planning to retire, but instead they recorded and released their first new album in 28 years.
"We either had to fold our tent or make a record," guitarist Glenn Frey tells CBS' "60 Minutes" in an interview scheduled to air Sunday.
"We were going to be done," Frey says. "And I wouldn't want to have it end ... where ... you're just sort of doing a caricature of yourself, you're just doing a tribute to yourself."
The band's new album, "Long Road Out of Eden," debuted at No. 1 when it was released last month.
"It came out better than I thought," vocalist-drummer Don Henley says. "I think a great many of the songs on it will stand up with the best work we've ever done."
The Eagles had a string of hits in the '70s, including "Hotel California," "Take It Easy" and "Life in the Fast Lane." Henley also had a successful solo career, but he says the Eagles are better together.
"There's a certain sound that we make when we sing together that over the past 35 years has become ingrained in people's minds," he says. "I can't sound like that with anybody else except these guys."
