Oh well, that's easy! Here are the first 16 bars:

I wish I were on yonder hill
It's there I'd sit and cry my fill
And every tear would turn a mill
Is go dt‚ t£ mo mhuirn¡n sl n

Si£il, si£il, si£il a r£in
Si£il go sochair agus si£il go ci£in
Si£il go doras agus ‚alaigh liom
Is go dt‚ t£ mo mhuirn¡n sl n

Hope that helps. If you still need the sheet music, let me know.

-- Aine (still languishing without her fada)
