Yes, they are available. The lullaby Fiona's mother sings is "Einini" available on "Singing in Irish Gaelic" CD book set. The selke song is "An Mhaghdean Mhara". It is a very old traditional song and if you will excuse my spelling, should be easy to find the lyrics to. If you search on youtube for "Niabh McElduff" , she is a darling young girl singing the selke song sean nos (unaccompanied) style. I have found google immensely helpful for lyrics. Hope this helps!
