I visited Lewes last year and that was a revelation, so currently Sussex is my first choice. Anyone want to recommend any other folk-friendly zones in South England?

No - if you have found Lewes, then you have found folk music heaven on earth.....

Two very lively folk clubs that put on top guests and manage to co-operate closely, a four-day festival in October, many tune and song sessions in pubs in and around the town, folk concerts & dances at the Town Hall and the All Saints Centre, ceilidhs, many dance sides dancing outside pubs that sell Harveys beer throughout the summer, regular all-day workshops on a variety of singing and instrumental subjects - all led by top performers, an excellent and very active West Gallery Choir. The Traditional Song Forum meets here in May.

An excellent local listing magazine that covers just about everything that goes on. Two listings websites with all the events listed throughout the area - and is kept up to date.

Lots of really talented singers and musicians involved with a lot of friendly and interesting people......

Of course, I could be accused of having a slight bias!
