6. Starland Vocal Band (1977): Grammys Stage a Key Party
For one brief shining moment in 1977, the Starland Vocal Band seemed like they had a bright future. The two real-life couples wrote a lovely ode to mid-day boning, and before they knew it, they had a hit all over the radio and a Grammy for Best New Artist. They sang "Afternoon Delight" at the ceremony, but never had anything close to a hit ever again and broke up by 1981.
