Christmas carols: Oi Betleem!
This is a Basque carol with English lyrics written by Sabine Baring-Gould. I found a version sung in the original Basque on YouTube, but it was absolutely terrible, so I'm embedding an English-language version, instead.
Just to remind you of what a truly funky language Basque is, I'm copying out the first verse and English gloss:
Ala egun zoure gloriak,
Hanitch beitu distiatzen!
Zoure ganik heltu argiak,
Bethatzen tu bazter guziak,
O Bethlehem! Ah! how your glory today shines out brightly! The light that comes from you fills every corner.
Like I said, I couldn't find a good Basque-language version on YouTube, but I did find this version by The American Boychoir at Yahoo Music.
