Joe Offer gets close here with the age thing. Burl Ives is an influential zero to I would think most baby boomers. The Weavers heyday kind of predates our record buying coming of age also. The facts about the Kingston Trio to these acts is almost night and day. The Trio sold considerably more albums and were by far one of the top acts in album sales from the late 1950s in to the arly 1960s. Burl Ives and The Weavers by comparison sold nowhere near the albums. Albums, not singles, exposed people to usually 12 songs at one time. The newer technology of the LP compared to singles alone exposed potential folk music lovers to more songs, plain and simple. Just by sheer numbers of the baby boomers compared to their predessor generation who felt the Weavers and old Burl were the folk music "it", the Kingston Trio plain and simple reached a considerably larger record buying and influenced public.

I am not discounting the Weavers as having an influence on the Kingston trio, but the Weavers did not create or play any part in the great folk "scare." The Kingston Trio created and sold more albums that influenced literally every record label to come out with their folk group, Peter, Paul, and Mary not withstanding. Keep in mind, Tom dooley won the grammy award in 1958 for best country and western song. Why, because folk music was not even a genre of it's own until them.

That's influence.
