I'm not sure about that. I remember someone criticising Arnold wesker's play Roots as naive. In the play Beatty (the country girl who has been working in the city and become 'sophisticated ' by her Jewish lover) . She's very rejecting of her parents when she returns to her rural Norfolk Home. Anyway she plays some classical music ( Bizet) to her Mum and soon they are both dancing round the living room in exuberant appreciation of the music.

Similarly in his play Chips with Everything. Its about some RAF national Servicemean. Its a dance and the boys are dancing round, getting drunk and fooling around to some vapid pop music. Much to the delight of the officers. But the 'hero' interrupts this with a rendition of The Cutty Wren. And he sweeps up a passionate response by the other recruits.

Wesker was criticised. Critics said - mere exposure to a superior cultural experience will not do the trick. Which I always thought chimed in with my experience of the world also.   the artist has (in my experience) to skillfully present his work with every artifice and aid known to man. Using all his cunning and intelligence. I loved Magic Lantern and the way Taffy Thomas and Tim laycock presented the ballads.

Still its only my view of things. I can understand other people think that only an uncompromisingly pure delivery will protect the tradition. I don't think both views need to be exclusive.
