From festival website: “This concert is NOT included in the weekend ticket. However, weekend ticket holders can swap the advertised Friday night concert (Flats and Sharps with Joli Blon) for Gretchen Peters for an additional £15 (£7.50 under 16s) — and still see Flats and Sharps, who will be the support for Gretchen, and then headline at the other night’s concert!”
