That little girl is amazing.
BTW Eddie,
since you asked. When we did cruise ships, we used the backing tracks I made myself, and set all-time revenue records in the lounge we played in. We were rewarded with a passenger sized cabin with a porthole, allowed to sell cassette tapes to passengers, and lasted 3 years on a 3-week contract which ended when Mrs. Notes' mom got sick, and we needed to jump-ship to become her caretaker.
But that's all off-topic
I mentioned various things that could be considered cheating and answered, “what would be the point?” That was to compare it with subbing Sinatra's voice over Anka's tracks.
Cheating or not isn't the question. My conclusion was:
We aren't going to answer the ethical questions here, although it's interesting to discuss them.
Me? I'm going to be amazed by the technology, and make a mental note not to believe what I see or hear. Then I'll go about my daily life, trying to get as much pleasure out of each day, for however many I have left. I have gigs to play, new songs to learn, food in the fridge, a roof over my head, a wonderful wife, I woke up this morning, and everything else is extra.
So I guess you missed the point.
OT, years later when they sold the ship, the entertainment purchaser on the ships told me that our revenue record stood the test of time, and was the highest on that ship, and her two sister ships, ever. He asked if we wanted to come back on. I had so many land gigs, and we were still taking care of mom, so I had to say, "no"
