AL,

I got up on the wrong side of the bed this morning. (Actually, I just
finished helping someone with a Master's degree turn the paper he's
trying to write into comprehensible English. That's worse.) The result
is losing the restraint that would normally deter me from this question:
how does someone who has reached the senior year in a university come to
write "tempo's" when he means "tempos"?

There's a very clever (but a bit over wordy) book by Lynne Truss (she's
English too) called "Eats, Shoots, and Leaves" that you would do well to
read. There's a panda story in it.
