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?

By the way, the Rockpile line-up was in place to record starting with Dave's Tracks on Wax 4 album and Nick's Labour of Lust (which is MUCH different than his first, definitely showing Dave's influence on Nick), both from '78, IIRC.
i was gonna offer "spirit in the sky", but notice it was released in 1969 (though still charted in 1970). "venus" and "vehicle" (ides of march) would fit the bill; likwise "hocus pocus" (focus) and "be thankful for what you got" (great tune).
