Apropos of what mcgrath said a while ago,two nights ago i was having a session with a dozen Kurdish guys and two of them went straight into an immensely long improvised song trading long strings of insults with each other. It was a riveting and hilarious performance ( though i couldn't understand a word being said you could feel what was going on all right). being able toshare in that in that in a soul-destroying asylum-seekers hostel in stoke was extraordinary. so i'm all for collective composition. sorry,mcgrath, still havent mastered the Shift Key.
