"Did the English bring the trad with them when they came to Britain"

When the Scotti arrived in 5thC & 6thC Britain did they teach the natives how to sing and play any known Scottish traditional tune? This is a bit of a daft thread. Various people have stated the obvious that English tradition is the tradition of the English people - just as Scottish tradition is the tradition of the Scottish people. You seem to be lumping the tradition of the modern so called Celtic nations together as if they are all one and the same thing quite distinct from the English tradition - but surely that is nonsense. Surely the Scottish tradition has far more in common with northern English than it would with for instance Welsh, Cornish or Breton? Much of the tradition of northern Scotland and the Northern Isles is heavily influenced from Scandinavia too.
