Although Chorlton is not technically in Cheshire and it isn't really December:

The Singaround at the Beech, Beech Road, Chorlton
First Wednesday of the month
is quite close

And

The Beginners Tune Session, at the Beech, Beech Road, Chorlton
Last Tuesday of the month
has just gone but will pop up again 24th February

Cheers
