She's Like a Swallow is an "English" tune according to my soruces.

The best folk rendition of this tune I have heard is on a CD called _Two Gentlement Folk_, Benjamin Luxon, Bill Crofut & Friends..

The CD is Copyright 1987 by Telarc International Corp.. Its a DDD recording that I really like.

Cant help you with Isabeu S'y Promene.
