I am currently updating the Community Choirs section of the Yorkshire Folk Arts directory at http://www.yorkshire-folk-arts.com/directory/choirs.html
Entries are free and open to all community Choirs in Yorkshire and what used to be Humberside ( North Lincolnshire and North East Lincolnshire).
Choirs need not specialise in folk music, but must be the sort of organisation which anyone can walk in off the street and ask to join, i.e. not church choirs or school choirs etc. which may require membership of that church or school. Have a look at the list we already have and it will give you an idea.
Please do not send information to this list, an online form is available at
or contact me direct at firstname.lastname@example.org
All the best
