Hi RTim, I love that song. It was in a book of songs which we sang in high school. The lyrics are not the ones you want.

The book was called Sing Care Away, and as I recall the song in that book starts, "Bring me said David the harp I adore. I long ere death calls me to play it once more."

The English lyric version may be a specific translation of the original Welsh lyrics. By that I mean, a Welsh speaking teacher could have translated the lyrics into English.

Do you remember the song being in a particular song book, or any more information which might help the search?
