This one is not an Advent-candle song, but merely a Christmas song that mentions candles. Still, I'd be interested in seeing the Swedish source (or at least having the original title):

A THOUSAND CANDLES

Swedish carol, tr., Evie Karlsson, tr. © 1977 Word Music
(from The Hymnal for Worship & Celebrations, no. 159)

1. We light a thousand candles bright
   around the earth today,
   and all the beams will shine across
   the heavens' grand display.
2. Yes over land and sea tonight
   the joyful message brings
   the birth of Him, our Lord and Christ,
   our Savior and our King.
3. Dear brightest star o'er Bethlehem,
   oh let your precious light
   shine in with hope and peace toward men
   in every home tonight.
4. In all our houses cold and dark
   please send your warmth sublime,
   the warmth that comes from Jesus' love
   this blessed Christmas time.

Haruo PS: I have one more I was going to add, a German song Wir sagen euch an den lieben Advent, which I only have in Esperanto (would like to see German, and English if it exists) but I see I left the MID2TXT file at home. Alas, Smyrna (as they say in Yiddish).
