I first heard about this group in the early 70's by reading an article in Playboy. (Yes they had some pretty good writers!). I had the band's first album Bloodshot. It was good but not popular. The group finally became popular in the late 70's. By then they were tired of each other but they managed to put together some good songs, including this one.
