The most challenging tune in Book 4, this is totally unrelated to "Farewell to Ireland". It's not at all unknonwn to encounter such confusingly similar titles in Irish music!
Normally played in A Dorian, but Tony has arranged it for gutar in E Dorian.
You can capo up to the 5th fret, but on the podcast there's no capo.
Tony has also brought the first part in some places so it can be played in one octave, giving it a more dynamic sound.
In some places there are triplets using three different notes. If these are problematic, you can isolate them and practice them on their own.
In the tablature, you'll notice that Tony plays the B on the 4th fret of the 3rd string in places, to make picking easier.
