It is all beginning to make sense! How the lost tribe of Israel ended up in Scotland!

Moses didn't actually give directions to the tribes. He issued woadstones for them to use to find their way. To most of the tribes he issued the high woad(stone.) Having told the Golden Chicken worshipping Picts to get lost, however, it behooved him to make sure they did just that. To the Picts, then, he gave the low woad. And we all know from the chorus to the song that the low woad will get ye to Scotland before the high woad.

(Is this now a music thread? Huh?)
