To Mg,
Sorry you had to cancel your trip. Must be very disappointing to have to do this.
However, if you do reschedule for a future date, here Is some information I looked up for you for folk music.

The Ship Pup on Solomon's Cane (265 Duckworth) St. John's
Newfoundland
Folk night at the Ship Pup
Folk music every Wednesday night 9 p.m.
Call for information at 1-866-576-8508`or 709-576-8508

I have never been there but at least you can keep this information to refer to if you go there at a later date and phone numbers to call.
