Years ago, Mrs. Notes and I gigged on cruise ships. We had our own lounge and entertained the guests.

In the big auditorium, the main shows had a 12-14 piece orchestra. But they played to a 'click track'. The entire show, including the orchestra and all the singers, except the main singer, was pre-recorded. The orchestra had a click track in their ear for tempo and played along with the backing track. The secondary singers had mics but they weren't hot. The main singer of the show sang live over the track.

The method was foolproof. As long as the lead singer could sing, the show goes on with no problem, and the audience is not disappointed.

I suppose a lot of arena type pop concerts are done with a lot of pre-recorded music and vocals. Why? If something happened and the singer can't sing due to throat issues (it happens), or a guitar amp dies, there could be thousands of people wanting their money back.

Music is a passion, entertaining is fun, but entertainment itself is a business.
