This single was released TWICE - once in 1982, and once in a remixed form in 1984, when it became a top 10 hit. Written by the three sisters, it's a song about.... being excited. What did you think I was going to say?
In all seriousness, it's a sexually charged song, which was atypical for a girl group in the early 1980s. This video is for the 1982 release, but is the gold standard, featuring all three sisters getting ready for a formal event. It also matches the lyrical content of the song.
You all came for the Jessie Spano version. I know this. Here it is.
