Music Sheets or Books with Celtic or traditional Irish songs (clarinet, guitar)

[CinnamonStar]

Anyone got titles you'd recommend?

 

I know there's google, Youtube, transposing from piano scores, but I'd like to see if anyone has something in mind.

I'm mostly interested into Celtic, Scottish and Irish folk music, preferably for the Bb clarinet or accoustic guitar, but I'll see if something can be done otherwise.

 

Music sheets, links to books or single titles are all good to me.
