This goofy but entertaining song was a favorite of my household when I was growing for quite a few years, and led to many a stupid dance. The Bangles were such a cool girl rock band, but they seemed to fade out of view a few years after the success of the album that this song was first compiled. People move on to different things, and I assume that each of the band members went off to start families, or try out new careers. Perhaps this is worth a wikipedia search after all, to see what happened to these chickies.
P.S. Yes, As a young girl, I did awkwardly attempt to emulate the dance moves for the song, but for some reason I always managed to mess it up in new and interesting ways, therefore showing how uncoordinated I am. However, this never removed my fascination or appreciation for this silly song.
