Not quite Telford, but within reach there's a session at the Breidden Hotel Middletown on the last Wednesday of the month.
On Thursday there's a session with Tony Weatherall in the Red Lion at Market Drayton.
As mentioned, the Unicorn Folk Club is at the Lion at Edgmond near Newport (was it that Newport you meant?) They have a guest artist next Friday, but you may get a floor spot if you contact Vicky in advance.
