if you are thinking South West UK have a look at cresby.com > festivals though from the OP I can see you won't like Shrewsbury. Loud, in a big field (did I mean a flood plain known to flood around Aug/Sept?) nearest hotel 30 mins walk away and not much SAR going on.

Upton upon Severn on the other hand is in the town, there are hotels and B&B and it is a small affair. If you like Morris - then it is a relatively big affair. Several venues cater for muso and one or two for singists. Say hello if you try it next year, (you will spot me)
