It was hard to choose only 5.....
- Mungo Jerry - In the Summertime
- Wild Cherry - Play that Funky Music
- Pseudo Echo - Funkytown
- Club Nouveau - Lean on Me
- Deee-Lite - Groove is in the Heart
by the way... going through One Hit Wonder Central I was surprised to see some bands up there... but then I guess it depends which country it is based in and was the definition of "hit" is... even so, I don't think Midnight Oil would be happy to see themselves on the list!
