May I recommend Nicholas Blundell's diaries(17th century) for a very interesting account of Lancashire life atthe time. Vey informative about piping, and also(as a bonus for southerners) he goes down to Oxfordshire on family business so we get some stuff on morris dancing as well.
The most interesting stuff to me was the fact that Blundell(a gentleman, of Crosby) actually socialised extensively with the piper he employed from time to time when he needed music. I remember discussing this very vehemently with Harry Boardman in the Plough in Galgate in the 60's. We both felt this fact said soemthing about northwest culture....we didnt feel southern gentlemen in 1650 would toddle round to the jobbing bagpiper for a meal and a chat!
