Does anyone know what the song was called or if there is copy of it on-line. At the end of one episode, Joanie and Chachi sing a song that they wrote. For some reason I've never forgotten it. it goes like this:

Days spend laughing in the sun,
Some crying in the rain,
That's how it goes - you and me had some love

I never thought that we'd become as close as we became
That's how it goes - you and me had some love.
