I know this isn't folk, but I heard Frank Sinatra Jr. perform at a
mall northwest of Chicago about 25 years ago. It wasn't that his
singing was really bad; there was just no reason for him to be there;
the show was divided between songs about great stuff like the superficiality of California culture (treated totally superficially, without a glimmer of humor) and cloned , but lifeless, performances of
Frank Sr.'s stuff. The man mumbled a couple of small,feeble attempts
at humor or raport, but he had the personality of a wet doormat.
