Estudiantina Waltz, Op. 191

The Light Classical station is playing the Estudiantina Waltz by the Cincinnati Pops right now. It sounds so familiar. I remember that tune from my childhood when they had a beer commercial on TV. If I write the words to the jingle, you may know the tune without hearing the music play. It starts, "My beer is Rheingold, the dry beer. Think of Rheingold whenever you buy beer. It's not bitter, not sweet. It's an extra dry treat. Won't you try extra dry Rheingold beer?"
I've never been a beer drinker but I remember liking the melody to that particular jingle. However, since I'm not a beer drinker, I have no idea how to spell "Rheingold". I do know how to spell Rhine wine which I prefer to any beer, be it bitter, sweet or extra dry.
