My husband insists he knew the minute he met me, at callbacks for a production of "1776." We were called back for John and Abigail, and we got the parts.
It took me a tiny
bit longer. I knew in the middle of a Sunday matinee, when I realized that it was no longer Abigail singing "yours, yours, yours, yours, yours" to John - it was me singing to the actor playing
John. I actually ran into the wings after the song and whispered to the stage manager, who's one of my best friends, "Holy crap! I just fell in love with J!"
