I need help finding who sings the song " on and on" from the 70"

It was a fella called Stephen Bishop

Do you mean from the 70's?

Jack Johnson sings On and On, but he's not from the 70's. If its not him you're looking for, perhaps you can type in some of the lyrics. It would help a bunch. :)

Not sure if this is the singer, but I believe that this is the song you were looking for;

Not sure is the title is: "On and On" or "Down in Jamaica"
