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?

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).
Not sure if it's already been mentioned, but I just heard:

"(Whoa,oh,oh...It's) Magic" by Pilot on XM radio, identified as 1975.

A natural for this list.
