Do not mock me! My husband is the drummer on the song Gloria, by Shadows of Knight. Technically, they also had a hit, You Can't Judge a Book by Its Cover, but I don't count that. So Gloria by SOK is my favorite one hit wonder song.
that stairway to heaven song by that one band... LOL jk jk.. umm id have to say well its not technically a one hit wonder.. but classical gas by mason williams.. he did a lot of other good stuff but that is really all he is remembered for by most
