New York, NY -- The documentary on The Eagles has an unusual moment for a rock film: it shows the exact moment they fell apart. "History of The Eagles" contains film footage of a political fundraiser in 1980. Don Felder didn't want to be there and Glenn Frey didn't like his attitude. The Eagles stayed apart for 14 years after that. Felder even breaks down while talking about that incident all these years later. Frey says they agreed to do the film while everyone was still healthy and could still remember things. "History of The Eagles" runs in two parts on Showtime tomorrow and Saturday.
