Donny, I used to hear that kind of stuff until I began demonstrating to my audiences how an arranger keyboard works. I would usually begin by playing a well known song using the keyboard as a grand piano, then begin adding accompaniment instruments, drums, bass, etc...
The irony of this was one night while I was performing at a location where I had been performing twice a month for 15 years, a lady walked up on stage while I was singing and playing and began asking me questions about another song. I stopped playing and singing instantly, looked her, never turned off the mic and said "Maam, I cannot talk to you while I am singing and playing." She blushed and said to her husband who was sitting at a nearby table "Herb, he really is singing - it's really him playing too." Geeze Herb! It never happened again. Sometime, you must educate your audiences.
Ironically, the same thing used to happen when I was playing a 12 string Yamaha guitar, sitting on a bar stool and singing my heart out in a smoke-filled bar room to a bunch of red-neck drunks. At least once every night I played, someone would inevitably come up to me and begin talking as if I could answer them while playing and singing. Most of the time, I just ignored them, but some of the ladies, especially the younger, drunker ones, would really get upset that I was not responding to their questions.
Just another day in the life of a musical entertainer,
Gary
