95 Songs of Summer, #72 - "Don't Stop" (1977)

If memory serves, this was the third big hit of off the behemoth that was Fleetwood Mac's "Rumours."  And of course, it has lasting fame because of its use by a certain candidate at a certain convention about 20 years ago. 

What I always loved about the song was the vocal interplay between Lindsey Buckingham and Christine McVie - there are points in the song where it is almost impossible to tell which one is singing, unless you're listening really closely.

"Don't Stop," Fleetwood Mac, from the summer of 1977.
