The Singers use a different translation and a slightly different melody than Lutheran Service Book.
And for another Swedish tradition, here is the same tune sung on the Commemoration of St. Lucia. Each year a girl is chosen to be St. Lucia. She wears a crown or wreath of candles. I am not Swedish and have only witnessed this once, so perhaps someone could enlighten us in the comment box.
Here's the tune found in LSB, to yet another translation.
Other highlights from this broadcast include Scripture readings from the historic lectionary for Advent III and excerpts from a sermon from Martin Luther preached on this day.
