We've got him at Linlithgow Folk festival, 12th-14th September. Tickets going well for his concert. Saw John Munro with him around 4-5 years ago on a previous tour: John has quite a high voice which makes for great harmonies, e.g. in "A Reason for it All" (AKA Claire)
Also saw Colcannon last year at Tinto (Lanarkshire); excellent band.
