The explanation, from Aspen Swartz:
I really enjoyed your post on that Icelandic volcano. (and being able to read Language Log, in general). I tried to learn to say it, which put it in my head, where it attached itself to a melody (John Kanaka, a sea chanty). So I wrote some verses to it, and sang it at our monthly sea-chanty where the group said I needed to put it up on youtube. The result is a crowd-consensus anglicization in the chorus — I hope it might be entertaining.
