Ooops ! Damn...this IS hard. You're right...let me rephrase:

"I don't suppose that many in my audience are trained instrumentalists, but judging from the ammount of requests for Karaoke, there seems to be a greated number of those who would sing, if asked."

Whew...... that sounds like a crock !

Anyway ... it's teh details of the instruments that I was talking about when I asked for 100% fact. I wanted to avoid things like:
"better" drums
"poor" build quality
"sweeter" sounds etc ......

Sigh...
