United States, to ensure the survival of the brewery. It resumed the export of beer in 1948—first to Switzerland. Löwenbräu's market position in Upper Bavaria, and financing made possible by its large real estate holdings, helped drive worldwide sales of their beer. In North America, Löwenbräu came to be considered the archetype of Munich beer, as shown by its presence at the Montreal Expo in 1967. In 1975, Miller Brewing acquired the North American rights to Löwenbräu. After two years of exports, Miller began brewing Löwenbräu domestically with an Americanized recipe, and exports of Munich Löwenbräu to North America ceased. Anheuser-Busch, whose Michelob brand Miller had intended Löwenbräu to compete with, called the attention of regulators and the public to the changes Miller had made to mass-produce the beer for the American market, changes which introduced artificial ingredients that would not have been allowed under the German Reinheitsgebot that Miller had advertised Löwenbräu as being compliant with. No regulatory action was taken, but sales of Löwenbräu dropped to the point where it was clear the brand would not seriously compete with Michelob for the premium-beer segment. The "Here's to Good Friends" jingle, originally performed by baritone jazz singer Arthur Prysock and then later by other various singers, including Clint Holmes, ran from 1977 to 1985. In 1999, the North American rights to Löwenbräu passed to the Labatt Brewing Company, which began to brew Löwenbräu in Canada for both the Canadian and US markets with the same recipe used in Germany. Labatt's production of Löwenbräu ended in 2002 and exports of Munich Löwenbräu to North America resumed, although on a much smaller scale than had been the case before the Miller deal. In 1997, Löwenbräu merged with Spaten-Franziskaner-Bräu to form the Spaten-Löwenbräu-Gruppe. Proposals to relocate the Löwenbräu brewery out of the Munich city center have failed, despite the company's international ownership. Today, Löwenbräu has one of the oldest beer gardens in Munich. In 2014, Labatt regained the Canadian rights to Löwenbräu and began brewing Löwenbräu at their London, Ontario brewery, producing a smaller, , can and soon after releasing a bottle. In November 2014, Canadian sommelier, wine consultant and writer Jamie Drummond called for a boycott of the Canadian made Löwenbräu in the online publication "Good Food Revolution", claiming the new product to be inferior, different in taste to the original.
