Fascinating stuff. The current Wikipediea entry on PB says he was a 'right wing folk singer' and in this respect it's worth having a look at what Dick Gaughan has to say about him on his website ( http://www.dickgaughan.co.uk/chain/peter-bellamy.html . Interestingly, PB's settings of Kipling's A Pilgrim's Way and The Land are invariably given a 'left wing' spin in singarounds.

Might I point you to my own performance of The Land at http://uk.youtube.com/watch?v=0J_eP5TmBHs - I posted this in the hope of inspiring the uploading of footage of the great man himself; still waiting!
