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

Ozz, Inna Gadda Da Vidi was 60's. I saw Iron Butterfly when the song was a hit.
Stuck in the Middle with You was really Gerry Rafferty, he had a string of hits.

What was the hit by 'Spiral Starecase'?
(Pretty sure that was 70's but maybe it was 60's also).

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.

Thanks Marty, and you are right, it is a great song.

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.
