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?

argent were basically the zombies without the great singer colin blunstone and were very good in their own right--sort of a poppier, less bombastic elp. i actually chanced to revisit them recently and was surprised how little they've dated. not exactly a one-hit wonder--their songs like "liar" and "god gave rock and roll" were big for other bands, and "dance in the smoke" (my favorite)is still an fm classic. there's a bunch of best-ofs and anthologies, which are probably the best place to start, but of the studio albums the first one, just called "argent" is probably the best.
Sealed with a Kiss was undoubtedly an earlier decade. Rubber Ball was a better song by Bobby Vee.
