Telephone Man From back in the 1970s, when you could still have a "regional" hit song.
→[More:] I remember this song being played on the radio, a LOT, and the singer was from an Atlanta suburb called Marietta (later home to the much-cooler band Guadalcanal Diary). It was considered scandalous at the time, but OMG the video is almost worse than the song, and I'd never seen it until tonight.
I'm pretty sure the song was (cruelly) longer than this, and this video is just an excerpt.
