Should have said that the pub contact details include a map. For those of you with sat nav, here is the address:

The Crown At Worthington
Platt Lane, Worthington,
Standish, Wigan, Lancashire WN1 2XF

Hmm, just looked at the website and can't find the programme, so the outline is that it starts Friday at 7.30, Saturday at 10 and Sunday 10.15 with Sunday songs or 11 with a ballad session.

Hope that helps
