What US brand was marketed as "The Champagne of Bottled Beers"?

Turns out it's Miller


and more than that, it's "Miller's High Life". Trust me see bio!. My best friend from the sixth grade on called me "High Lights" for thirty years and would not be corrected, so I stopped trying. He came from a staid Long Island conservative Republican Methodist family, could trace his ancestors back to Germany 1591, never drank nor did his parents, knew only the shape of the sound of the words but never saw a label. A forgiveable mondegreen, I would say.
