I was 90% sure that I knew commercial you selected before I read any further.
I think that jingle has been in my head (intermittently) for the last 15 years. For being a radio/TV jingle, this is one of the few that doesn't make me cringe (in contrast to say jewelery store jingles on the radio).
My sister works in marketing for Pepsi and acknowledges that this is as good a cola ad as any made.
I probably only drink 2-3 Cokes per year anymore due to a change in personal tastes (away from sweet flavors) but I still think that a fountain Coca-Cola is an unbeatable beverage with certain types of food.
