Thanks for that link. It's wonderful. Scroll up to the top for the revised version of John Kanaka:
"I thought I heard the old man say
Eyjafjallajökull blew today
we'll fly tomorrow but not today
Eyjafjallajökull blew today

Both a lovely updating of an island chantey and a lesson in how to (sort of) pronounce Eyjafjallajökull.

Also some other good suggestions for volcano chanteys in the discussion.
Blessings,
Barbara
