At This Moment by musical1

The first time this song was ever heard was before it was released as a single and Alex Keaton was dancing with a girl like it was the last dance they would have together or something---when people heard it, they phoned in and the phone calls led to it being heard on the radio eventually. I was there. :-) (Meaning when the episode first aired and was one of the people who called in to ask who the artist of the song was and where I could buy it!) :-)
