Telford - look in cresby.com the Boat at Jackfield hosts an Irish session on Thurs, plus a few things a bit further North East that Ms Lemon goes to round Bishops Castle.
Ones I don't list are Tong (Fri) and Mike Raven's session at market Drayton (he has a Website)
Let us know of any sessions that you go to - or any in my vague area.
