Released: September 1980

I don't have a single favorite song of all time, but I do have a very short list of songs that make up my top 3. They seem to rotate as #1 based on situations I am in and what my mood is that particular day. Hold On is one of these 3. The other two are:
Crystal Ball by Styx, and Love Is Alive by Gary Wright.
