Here's a temporary midi of Carol of the Bagpipes. After more information, I'll post the words and midi to the DT.

I think the first two lines are a dead ringer for "He Shall Feed His Flock." (Imagine it just a little slower.)

The line starting with "Never so brightly..." sounds a bit like "Bambino Divino" to me.

Then the last line,"A message to the Magi..." sounds a little like that instrumental passage in The Messiah just preceeding "He Shall Feed His Flock." Anyone know the name of that, or where I can hear it online?
