Thank you, Alison, for your effort. The problem is, actually I´m looking for the intro the Dubs played in their version on their 25th anniversary-record. It´s a variation of the melody-line played in double speed.
I started playing the fiddle very recently (about one year ago), and while coming from a different kind of music and never learned to improvise I´m fascinated by the way John Sheahan (and every fiddler also) really plays with tunes and melodies. By listening and trying to copy it I tried to learn a little bit about improvising Irish tunes. But I still have many difficulties for I played classic music too long and the learning of playing music exactly the way it´s notated was too intense.
That´s the point where I came across the Dubs version of Oro Se Do Bheatha Bhaile and also my whole story.

Regards, Carl
