This audio track could be considered to be a great lost Credibility Gap artifact. I found it years ago on a Public Service Announcement LP entitled Vote '72. Though it sounds like it's merely a vocal placed on top of a pre-recorded pre-licensed music bed, it's still a lovely example of lyric writing and patriotic ennui. Introduced by Harry Shearer, the identity of the vocalist is a mystery to me. This advice is still just as timely as it was in 1972.
Click on the title and enjoy VOTE 'TIL IT HURTS.
