Do be carefull. I have Sean Tyrrells first album with the song "The Isle of Innisfree". The lyrics are incorrect and the melody format is also wrong. I have a copy of the original sheet music since 1952.
It's a shame because he sings it with great feel.

Incidentally I recently found a great website for this song and info on its composer for anyone interested. www.stoneandfarrelly.com
