You're not Lutheran, I'd wager. We don't sing things a few times. Lutherans are expected to handle a vast quantity of music, to be able (almost) to sight read, and to sing songs they've never heard before. Getting the lyrics is taken for granted.

My husband, a Catholic, came home from choir after several years and said "I'm beginning to think that someday I will be able to look at a line of notes and figure out how the music is supposed to go."

I told him that someday he might qualify to become a Lutheran.
