If my Basket of Turf is the same as yours, then it's #735 in O'Neill's, a double jig in the key of G. However, when I play it, it seems to me that some of the C's ought to be C#'s, but not all of them. I leave that up to you.

There is a pick-up note, an eighth note on low E. After that, the chords I play are these: (each line of type equals one measure of music)

A part:
Em
D
Em
D Em
Em
D
G
D
(repeat A part)

B part

Em
G D
Em (or C)
B Em (or C)
Em or C
G D
G
D Em
(repeat B part)

Measure 12, the one with the B in it, has a D# as its second note. That's why it needs a B, not the usual Bm.

Playing the C chords in the second part adds sweetness and sparkle. Try it.

Let me know how this works for you.
