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?

Dobie Gray-"Drift away". I am not sure if he had any other hits, but this is one of my favorites and I don't remember seeing it mentioned in this thread.
"Drift Away" and "Black Betty" are good choices but(IMO) don't enter my top ten. Gerry Rafferty had a mega #2 Billboard hit "Baker Street" in case you forgot? "Feelings" not a bad choice(don't like song)but have no problem with it being a top ten possibility along with "Chevy Van"/"Shannon"/"Please Come to Boston".
