Crest-fallen

Ah, remember when families had crests? Did they also have songs? Deb and I were discussing family songs the other day although I'm not sure how!
Our family do have a family song "Running Bear" - or so I learnt at the family reunion back in 1990. I was sufficiently not curious enough to ask the history of the song, or why that particular song had been chosen. Or why our family song should be about two lovers who try to reach each other across a raging river and die trying! I'm sure copyright issues come to play here - so here's a link to the lyrics
Deb was saying that the family she knows sings its song at all major events. They'll be there and then someone will sing the starting note and everyone will join in. At first, she said, she had no idea what was going on.
I can't remember our family actually ever singing the song. Maybe it's time. We're planning an immediate family reunion just after Christmas and it's time the younger members were apprised of this particular heirloom.
