I was invited to watch a friend's choral conducting in action one Sunday, years ago. His choir consisted of a group of children, gathered in front of a warm and welcoming congregation. They sang in unison, save for some short solos woven in here and there. Soloist after soloist took a step forward, sang their piece, and then immediately stepped back into anonymity.
Then... instead of taking a timid step forward, the next soloist literally leaped out of line. Sashaying and shimmying, hands clapping over head, she danced through the aisles as she sang to a room of surprised and delighted adults.
I was surprised and delighted as well. But not nearly as much as when I caught a glimpse of a previous soloist turning to a choir-mate to ask "You can do that?"
