The Kingston Trio also did a radio commercial for Ry-Krisp, "the bite-size cracker," and the Limelighters did one for L&M cigarettes:

Start fresh
With L&M
Stay fresh
With L&M
Unlock a whole new world
Of fresh smoking pleasure.
Start fresh, start fresh
With L&M.

They did another L&M commercial where they sang "They give you flavor, flavor, flavor." In a 1988 phone interview either Alex Hassilev or Lou Gottlieb told me that when they were goofing around at that recording session they would sing "They give you cancer, cancer, cancer."

And Tom Glazer told me in a live interview in 1987 0r 1988 that he was still receiving royalties for the Castro Convertible jingle but it was at 1950s rates so it wasn't much. This from the man who wrote "A Dollar Ain't a Dollar Anymore," so he should know.
