I agree, Paul. With the possible exception of superior backing, it's no different than Liberace, Billy Joel, Elton John and a host of other top entertainers on stage with just a piano and singing. Add an attractive, female vocalist and there are lots of duo acts out there that make a good living without the aid of a PC and other gadgetry. I, personally, have made hundreds of dollars as an OMB entertainer.

Cheers,

Gary
