They're on the final tier already (in fact they might have crossed into it after the announcement), they can't need a ticket sales push right now. Best I can come up with otherwise is it's part of the FJM tour rollout, what with his regular dates announced on Tuesday and Moseley Folk Festival yesterday. It might explain why there's so little depth, as in everyone announced you'd expect to be late afternoon at least on Woods/Garden or up at/near the top of Big Top.
And people wonder why efestivals is no longer the place to come and post rumours and information they have had passed to them.
If I was genuinely in the know I wouldn't bother coming here in a month of Sundays as I know how much sh*t I'd get.
