There are good clubs in the Southwest ...
Swindon (every Friday; shuts down July/August but unofficially continues with singarounds throughout that period) plenty of excellent guests and resident legends Ted & Ivy ...
Devizes (Mondays) - Bob & Gill Berry's club - terrific guests (about once a month) and enjoyable singarounds otherwise. Definitely deserves supporting. Great for choruses!
Bradford-on-Avon (Tuesdays) - no guests; very popular, continues throughout the year.
Highworth (twice a month - Wednesdays) has occasional guests, really friendly and well-established club.
Corsham (Thursdays) is terrific - really good attendances every week, and a really high standard of floor singers and musicians ... guests once a month or so.

Also : The Nova Scotia (Bristol) - good variety of guests, and some
outstanding floor singers/players every week. Every Monday; and occasional Saturday guest nights as well.

This year I have also visited Folk in The Vale (1st Friday of the month) in North Dorset, and Mary English's monthly session in Bath;
all these places are within an hour or so's drive for me, and I'd recommend every one of them - they are all really welcoming to new visitors.
