Many years ago, I remember hearing an excellent remix of the song on the radio. It was Gettin Jiggy With It with Will Smith saying his lyrics, but the song focused more on how the original song's flow / beat went (The Na Na Na Na Na Na Na part was left out) and THEN some of Sister Sledge's lyrics played at the end about them being in San Francisco and all that. I guess you could say it was an early Mash-up. Does anybody know what remix I'm talking about or who made it at least? Thanks.
