When you perform 5 to 7 days/nights a week, you need backups available on the job. I'm fairly confident that if my keyboard were to ever drop dead on the job, I could finish the evening just doing karaoke with MP3 files on my laptop.
If my amp were to drop dead, I carried a spare amp with me all the time, and I could be up and running within a couple minutes. Also carried spare mics, spare cables, spare power supplies, and everything was protected with a very high quality surge protector with a ground fault indicator.
I know that Donny carried spares with him as well, and he could easily continue through the night on his vocals and MP3s, or just DJ the remainder of the night.
I guess the worst thing that could happen to me is I were to drop dead in the middle of a performance.

This happened to at least three of my friends during the past 10 years, one of which, Jimsax, was a forum member.
All the best,
Gary
