Just a reminder about the origins of our 'yellow ribbon' tradition here in the USA. While yellow ribbon folklore dates back to the Civil War or earlier, it was the 1973 Tony Orlando and Dawn song, which made a dramatic comeback eight years after being recorded, that is responsible for the ribbon's current ubiquitousness. When the 52 American hostages held in Iran returned home after 444 days of captivity on January 20, 1981, the song--about a convict who's served his time-- was played throughout the land as a joyous homecoming theme.
It's true, boys and girls. You gotta love this country!
