They were in the wrong venue. They might have been in the Queen Elizabeth Hall where at least they would have had better acoustics, closer contact with the audience and maybe a sound technician who could tell the difference between micing up a bunch of folk musicians differently from the needs of the Halle Philharmonic. But the folk musicians disdain for their London audience was clear. And I will say it again they mumbled their intros. and words. We didn't get an encore either.
