Pavane, Green Grows the Laurel is in the same group as ...lilacs- and as broadsides I have seen go, earlier. No real data on this, however.
Odd, in all the versions, I have never seen the words to the one we sang as kids in New Mexico and Colorado. It ended "Green grow the lilacs on the Oregon Trail." Perhaps only this line was different- I can't remember now. Anyone else know of this wording?
