I remember once on a live John Peel session they were playing so quietly that an automated 'emergency' song - some cheesy pop chart hit - suddenly started playing. F***ing Radio 1 eh...
I have their Christmas album but have to admit I was never the biggest fan. In my more immature youth I may have also written them off for being Christian or 'uncool' (like I even knew what cool was) - shameful I know. I think as I get older I will reappraise them. I like the videos you posted.
