Burl - That's Cornelia Froboess. Shes's still alive and after a career as singer (e.g. together with german "rocker" Peter Krauss) she became an actor.
He first successful recording was "Pack die Badehose ein, nimm Dein kleines Schwesterlein und dann geht's hinaus zum Wannsee.."
The song you mentioned could be "Nimm uns mit Kapitän auf die Reise, nimm uns mit auf die weite, weite Welt...". Originally this is a sailors song sung by Hamburg's Richard Germer and others. He is a very early folk-like singer from the 50'. He used to play a lute. Other famous songs performed by Richard are "So was Dummes", "Rum aus Jamaika" and "Geh'n wir mal zu Hagenbeck".
