Hadnt even noticed that greg, had a listen on you tube , they are very similar no doubt about it, think the main difference is the notes that they start on,  banshee starts on low e and this one starts on high e,, also in the a part the tenpenny bit goes to f sharp and g,  in the banshee it does the same but in the b part, doesnt make much difference though, still think its a better version than I originally learned. On the session where I just looked it has them down as two different tunes altogether, mind you there are multiple ways of playing either one of them, good point though.

You were bang on Emily, double jig in  A Dorian, you have a good ear, no mistake:)

No prob I enjoy the banter, lots of tunes are very, very similar no doubt about that at all. I have  noticed how tunes grab parts from other tunes as well, I was actually going to start a thead on this very thing, thought it might make an interesting topic,.

I think one of the reasons a lot of tunes are more or less the same, and the reason why they have different names is to do with Ireland itself. At one time most people never travelled more than 5 miles from the place they lived in their entire lives, and when they did and took a tune with them, it would be played and altered, and maybe given a different name when the original name was forgotten. I touched on this a long time ago when I mentioned that there was no correct way to play any Irish tune, as you could hear something like the Banshee in one place and if you went to another town the tune would be changed. You also got the thing hapening like I did were a tune would be altered as it was being played because the musician thought it sounded better, someone else would hear it and then play it as he had heard it, then add a bit himself and before you know it you have a new tune. I even do it myself adding ornaments were I like them, fergal scahill does it a lot. If you listen to his version of captain O Kaine it doesnt sound much like other recordings, but is brilliant because of his playing and ornaments.

Thanks mouse, its a simple tune but deceptively difficult, I think anyway. 

Thanks for taking a look Sasha, worth just picking out a tune and having a go,, its great fun.

They are alike, but are different tunes, bezt way to see it is look at the session, like I saId to greg, there are only a couple of notes different, it may well have started as one tune but as it was played in different areas aquired a new name, iin the pub, and then split into 2 different tunes, only my thought though and could be wrong:)

I totally agree, I like the history of the tunes and talking about them, its like a cultural history of the people who made the music.
