...and what about our own Kevin McGrath?
He's probably too modest to bring this up, but I heard him sing his song about the Chinese kids asphyxiated in a container at Dover in a session at Sidmouth last year, and you culd have heard a pin drop. The reaction from everyone afterwards was a muted and rather emotional "Wow."
It's powerful stuff - and it's a protest song about something that happened just a year ago.
