Los del Rio had actually recorded "Macarena" as early as 1993, but the song took off like a runaway rocket three years later, thanks to a Miami DJ.
The resulting revamp of "Macarena", with the remix credited to the Bayside Boys, hit #1 on the Hot 100. Take a close look at the ladies in the video, and you'll find future sitcom star Tracie Ellis Ross (later of Girlfriends). Hey, I didn't know until I did the research!
"Macarena" was SO hot, they set a record for the largest group demonstration of the dance at, of all places, Yankee Stadium. I kid you not. Los del Rio also produced a Christmas version of the song. I'll see if I can find that come December.
