Singing catcher

[Dakota]

ASA rules, 14U. Fall ball.

One team from a metro-area suburb with a "wealthy" reputation. The other team from a small town well away (~80 miles) from the metro.

Small town team comes to bat. Catcher, in her crouch waiting on the pitcher to begin, starts singing "Old McDonald Had a Farm."

My question - what would you do if

a) It is between pitches, or
b) It is after the pitcher has started her windup.

I'll tell you later what I did.
