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

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.

"Baby It's you" by the Group Smith

Sealed with a Kiss, by Bobby V.

Sealed with a Kiss was undoubtedly an earlier decade. Rubber Ball was a better song by Bobby Vee.
