Really old treehouse tv show?

My friend and I were talking about a really old treehouse tv show we both used to watch when we were kids, but we can't, for the life of us, remember what it's called! All we remember is that part of the theme song was like "ohh it's great to be pirates,sailing the ocean blue with a pirate ship and captain kidd no rules no naps no shoes" Does anybody remember what it was called and where we could find a clip of it?
