Not only the commercials, but also movie themes (Magnificent Seven), and contemporary pop music (No Matter What Shape) are given a chamber jazz arrangement by the jazz legend Benny Golson. Good music, I like it.

PS. "No Matter What Shape (Your Stomach's In)", an instrumental piece that Sareceno had lifted from a then-popular Alka-Seltzer TV commercial.
From 1963 the [Magnificent Seven] theme was used in commercials in the USA for Marlboro cigarettes
So I guess all of this music really is from commercials.
