What is your favorite 1 hit wonder from the 70's?


Many on Audiogon agree the 1970's was the best decade for popular music. Whether it was the quality of songwriting or the diversity of music. The decade also produced many unforgettable 1 hit wonders. My personal favorite is Afternoon Delight by Starland Vocal Band, what's yours?

Not necessarily my one and only one and only but certainlyh worth recalling, Blues Image's "Ride Captain Ride". Don't think I saw that posted previously.
I believe that Spiral Staircase charted with "More Today Than Yesterday". Great song, but late '60's IIRC.

Nobody mentioned yet.. but from my part of the world, hits like..

-Do That To Me One More Time (Captain & Tenille)
-Please Don't Go (KC & The Sunshine Band)
-Love Is In The Air (John Paul Young)
-First Time Ever I Saw Your Face (Roberta Flack)

Are some that certainly made their marks during the '70's--while not exactly a one hit wonder, but..
Miss those great eras, the '70s & '80s.
You know, reading and being reminded of some of these songs, I'm not sure why we are nostaglic. :)
