Don F. I'm pretty sure they did not predate the Kingston Trio, who had a 45 of "Tom Dooley" and "MTA" by '56. But I do recall an album of theirs coming out in '62 or so. Is it possible that they didn't get into the studio until after the Trio?
You also raise a question in my mind. Who was the gal from the "Michigan School of Big-Boned Women" who had a voice like a tugboat in mating season? A voice deeper than Ronnie's, and sort of a pre-Cass Eliott. And didn't Dave Guard do an album with her before falling off the earth?
