I posted the trailer to Gunhild Asting's It's Hard To Be A Rock'n Roller with no explanation a couple days back, simply because I was in awe ... here it is again, with all the relevant info.

A documentary about the music group Merkesteinane from Volda in the region of Sunnmøre. The group consists of mentally challenged individuals. The band has ten members – all of them with distinct personalities, abilities and, not least, with widely differing ambitions. Eight of them are disabled, two are participating leaders; Øivind and Jostein. With generosity, cheerfulness and love of music, the band has survived for 11 years. They have become an odd social and cultural institution in the Volda district.
