I had some fun in service with a CO named Lubomir (Luby) Sawkiw.
One time I found myself alone in the field service with him and his wife Pat, and he took me to a McDonalds and started a long conversation about the TV series "Star Trek -- The Next Generation" and all the characters he liked.
Another time between morning and afternoon service when he visited, he and I did competing versions of Beethoven's "Fur Elise" on the piano. He was an accomplished musician.
If memory serves me right, he was also the same one who popped in a tape of "Beauty and the Beast" songs while we were between calls one morning.
Luby was a pretty fun guy, in spite of being a circuit overseer.
