"'Natalie' (whether that was her name or not) was a Studio 54 dancer in SoHo who contracted AIDS, and he is encouraging her to get her "last dance" in before it's too late - i.e. to live her life to the fullest while she can."
I found the song itself beautiful, with the lyrics and the music. Now I find it even more beautiful as it is a song written to a dying dancer. Encouraging her to continue with her passion of dancing and immortalizing her at the same time. Sigh~
