I'm a bath & camp-fire singer, migrated to Folk Clubs in old age.
I went to my first folk club, NNNP-D, and sang Campion's "I care not for these ladies." There was some lovely singing in the club, but all deeply melancholy. Their most cheerful song was the "final rousing chorus" that might have been "The fields of Athenry."
It was several years before I went to a folk club again, and found that smiling was not actually forbidden.
