One thing I have learned over the years is that a lot of singers write jingles to pay the bills. Folk singers do this a lot - they write songs for ads, or for other people, and they make their money behind the scenes, and that pays for what they want to do, which is sing folk music, which would never pay the bills. It's kindof like stamping - the Day Job pays for it.
So Barry Manilow has a song he calls his VSM - Very Strange Medley, which is a medley of a bunch of his commercial songs. In my never-ending effort to educate those of you who have probably never even heard of the man, have a listen. This is not a video - just the song. The picture is the album cover of one of his Live albums, and yes I have it, and yes, it is round, and vinyl.
