If they had three European dates announced and have cancelled two they absolutely aren't fulfilling the other one.
However, Friko (who pulled out last year) have today put out a graphic for their rest of the year dates including the Thursday of GM.
Ah that's a big shame about The Beths. Was excited to see them for the first time since the last time they played Green Man, which is some time ago now - 2019 I think?
