I don't know the pub. I'm not aware of any sessions in Cromer either. The nearest folk event to Cromer that I know of is one in the Burlington Hotel, Sherringham on the second Wednesday of the month. It mostly a sing aroud but the do have the odd instrumental too. I've not been in a while (I tend to make my weekly "fix" an Irish instrumental session in Norwich) but it's a very friendly place.

Went into the White Horse yesterday and bumped into Morticia and Gomez which was a nice surprise.
