Peg:

When in London, go to Cecil Sharp House in Camden Town and pick up a copy of their directory of folk music clubs in the UK. It'll tell you where folk clubs are meeting all over England and includes phone numbers so you can check in advance to see if the venue has moved. We had very good luck using it twelve years ago. It's not so good for Scotland, Wales and Northern Ireland but seemed to be very accurate for England.
