Some more YouTubery:
Ajax commercial from the 1950s. My mother said that my father, who sang bass in a barbershop quartet, would sing this song around the house.
Flintstones Winston Cigarette commercial. Have a butt with Fred and Barney.
"I Love Lucy" Philip Morris commercial. Or, have a butt with Lucy and Desi.
Mr Clean commercial from the 1950s. The song is a classic.
Ballantine Ale commercial. Another great song.
You know, things have moved around a little on my posting screen.....
