the short answer is yes
for everything
your dance group is an unincorporated association
and so the members are liable
for the whole lot
( no limitation see ?)
I cant remember if each member is liable for the whole lot
( jointly and severally liable)
if you dance group is charging dancers then remember there is a contract side to this ....
and look there is a gobmint URL about it
https://www.gov.uk/unincorporated-associations
and here is a book which is a bit of a boring read
The Law of Unincorporated Associations and Similar Relations (Classic Reprint) Paperback – 5 May 2017
by Sydney R. Wrightington (Author)
I think this is the one I used in 1990
it was as they say all such a long time ago
