I tuned the **** piano. Took a couple of days, a tuning fork, a 1/4 socket, a 5/16" allen wrench, two rolls of nickels. I got free meals for those days, Hong Kong authentic Chinese food, but it didn't kill me.
And yeah, people with no pitch nor musical education still respond to those carols Grandma ( or the English tutor, in the case of my Hong Kong in law) used to play. They are responding more to the people they remember, than the music per se, IMHO. Whatever.
