I'm gonna go Kool and the Gang only because our band toured with Wyzard and Dion from Mother's Finest and they would play Jungle Boogie right before they took the stage. That song has fond memories for me now. They were great guys and top drawer musicians. Wyzard is an insane bass player and Dion was a great drummer and good ping pong player. We did sixteen dates or so with them and at every show Wyzard would say, "where's all the people?" He wasn't used to playing dives to scattershot crowds.
When I was in seventh grade or so, Celebration was the big hit, they played it at the county fair and I thought it was great. This was in the days that I would listen to Casey Kasem's top 40. Soon afterwards I would see Rock and Roll High School for the first time. Ah, the Ramones... no more top 40 after that.
The EWF singer is super amazing but the music never really did too much. I remember George Clinton saying something to the effect that they were, "Earth, hot air and no fire."
It's really a toss up but I'll go with Jungle Boogie for the MF guys.
