Once lead up as twos lead down turn alone lead back
Neighbors lead out turn alone lead back
First corners change RSH Second corners change RSH
with neighbor fullback come forward pass through
First corners meet and face away in the middle
Second corners meet face away
clap and turn single to place
Circle left once around

Valentine’s Day customs, like many other folk and rural observances, had been discouraged under the Commonwealth, and the new figure and title for this cheery tune reflects their revival. In his observations on England in the 1680s, Maximilien Misson (1650-1722) said:
On the Eve of the 14th of Feb, St. Valentine's Day, a Time when all living Nature inclines to couple, the young Folks in England, and Scotland too, by a very ancient Custom, celebrate a little Festival that tends to the same end: An equal number of Maids and Batchelors get together, each writes their true, or some feign’d Name upon separate Billets: which they roll up, and draw by way of Lots, the Maids taking the Mens Billets and the Men the Maids; so that each of the young Men lights upon a Girl that he calls his Valentine, and each of the Girls upon a young Man which he calls hers: By this Means each has two Valentines: but the Man sticks faster to the Valentine that is fallen to him, than to the Valentine to whom he is fallen. Fortune having thus divided the Company into so many Couples, the Valentines give Balls and Treats to the Mistresses, wear their Billets several Days upon their Bosom’s or Sleeves, and this little Sport often ends in Love.
