HISTORY OF THE EAGLES
Showtime, 6:55 p.m. ET
This documentary on The Eagles - the musical ones, not the national-emblem ones - originally was televised in two parts, both of which surprised me by how thorough, interesting and entertaining they were. Now Showtime is showing both parts in one big three-hour gulp - and it's quite a feast. It's worth it just to see vintage footage of some future Eagles backing Linda Ronstadt on a small club tour.
