I found a website that has some really old tv ads on it, including two of the "Teaberry Shuffle" ads with the Herb Alpert music I was talking about. Go here and you can live the experience yourself. Visit the other pages, too - the "drink" page has a Kool-Aid ad with The Monkees that, oy vey, I remember seeing as a kidlet.
God dang it. I really am old.
