The particular campaign I was thinking of was Schaefer Beer from the 60's. (A quintessential Northeast regional brand headquartered in Brooklyn until the 70's before moving to the Allentown PA area. Most people "of a certain age" who migrated to California from the Northeast probably remember them.) "Schaefer ... is the ... one beer to have when you're having more than one." With sings or instrumental solos by artists like Eartha Kitt, Louis Armstrong, Stan Getz and Astrid Gilberto, Benny Goodman, the Highwaymen, etc. Great commercials to sing along to. Just a classic ad campaign.So true. To this day, 50 *years* later, I can still sing the jingle for Gensler-Lee Diamonds. Heard their ads a zillion times on KFRC/San Francisco. So well produced and catchy, the spots sounded better than some of the actual songs played.
