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?

Hate to be the "Ken Jennings" of this thread. Golden Earring Hit #10 on the Billboard singles chart with Twlight Zone in 1982. If your unfamiliar with the White Lion Radar Love cover version(1989)... you will discover the guitar playing of Vito Bratta is pure ear candy!
Noticed not one mention of You Light Up My Life by Debbie Boone. Other religious based songs include Day By Day-Godspell(Robin Lamont)and Hand In The Hand-Ocean. Mr.Greenbaum wasn't the only one to cash in on the Jesus craze!
I just heard Argent "Hold Your Head Up" on ATT Music Channel and then found out they never had another charting US single. "Hold Your Head Up" peaked at #5(Billboard)in 1972. Not sure if it was mentioned in previous posts. FWIW could anyone comment on the music content/sound quality of the 7 lp's they released.
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.
