ACROSS the bridge, and hand-in-hand,
He promised her he would return,
And she said she would wait for him,
And so, they did.
EACH kept their promise, then made more,
Upon this very bridge they stood,
Though they’ve been gone these twenty years,
Sixty-four living trace their lives back
To one couple standing upon this bridge,
Then standing upon their promises

This is a lovely testament to constance and continuity!
