The 2016 edition of the John Martyn Gathering in Yorkshire will take place on the 24th, 25th and 26th of June. Location is the famous Green Dragon. The organizers promise three days and nights of John Martyn related activities. The program features some fantastic artists, special guests, and also an open mic stage and guitar workshops.
Weekend tickets cost 30 pounds. Which is 'cheaper than Glastonbury, and you're guaranteed to see everything.' This event is on a much smaller scale, of course.
Rooms can be booked directly at The Green Dragon (details below) and there's also a camping available.
