Glyn,
I havae been back in the USA for the past 2 years (wreaking shanty havoc on Chicago and now the DC area).
When I was stationed there (99-2000), we had quite a revival going. 2 different folk groups: one group, the older more established event, was run by the Irish crowd and included blues (with amplifiers no less). The second crowd was based out of folks villas and rotated duty every couple of weeks ... I think they still meet (I'll have to launch an email to the Hash House Harrier crowd ...).
Others, like me, have moved on to various parts of the world. I'll never forget the delicious irony of ANZAC Day when 3 of us sang for the Aussies and Kiwis -- not one of us was born in Australia (2 POMs and 1 Yank with an English accent ... go figure).
The Kuwait Theater (and Panto) still goes strong from what I have seen. Yep ... there's stealth culture in Kuwait!
Alhamdillolah!!

By the way ... BAZ ... see you in July ... coming to visit Cornwall and the West Country.
Cheers,
Brian
