It must have seemed quite the fairytale romance at the time. Peter Allen, the Boy from Oz, all of 23 years old; Liza Minelli, two years his junior; both of them just on the cusp of the stardom that would define their later lives; neither of them married before.
The marriage would last a little over seven years, ending in divorce in July of 1974. Minelli would marry another three times, divorcing each time. Allen would never marry again, becoming more comfortable and out about his sexuality, and spending most of the rest of his life in a steady relationship with his long time partner Gregory Connell.
