Yes, this is a nice topic!
Karen, I have never heard of Mary’s Boy Child, and will look it up. Thanks for introducing this song!
I am working on a medley of two songs to play for Chanukah: Ner Li and Hatikvah. Since one is in G major and the other is in e minor, I used the chord progressions in Tina’s Celtic Circle DVD to modulate from one to another :-)
I’m in an Irish band, and for an upcoming gig, we are working on a medley of Sevivon – another Chanukah tune – and the Congress Reel – which is Irish. Should be interesting!
