I really have to hand it our readers on this one. The Captain and Tennille clearly deserve a spot on this list, but you didn't go for the obvious choice with "Love Will Keep Us Together" or "Do That to Me One More Time." No, you wisely went with "Muskrat Love," by far their hit that's aged the worst. The song (originally called "Muskrat Candlelight") was written by obscure country-rock artist Willis Alan Ramsey in 1972. America covered it in 1973, and the Captain and Tennille cut their own version of it in 1976. The song isn't some sort of analogy. It's about actual muskrats falling in love. They played it at the White House in 1976 when Queen Elizabeth II came for a visit. It's unclear why the Ford Administration thought that was a good idea. If they came a year later, Jimmy Carter would have probably pulled in a better act. Anyway, the Captain and Tennille rarely perform together these days, but they're still happily married. They're one of the few pop duos in history to actually have a long-lasting personal relationship.
