No keyboard on stage?
Where are you going to hide?
Believe me, even rehearsing I felt naked ... fortunately for all concerned I wasn't ...
Can't imagine what it will be like in front of an audience ... I have NEVER sung karaoke, even when out with friends prodding me to do it ...
forget karaoke ....just memorize the lyrics .....get a wirless mic and go out in the audience and give em hell!! good luck~!
When I said karaoke, I really meant just SINGING to back up tracks ... I know all the lyrics to the songs I am singing ... just don't have the wireless mic - yet

... we'll see how this works out and where it might go from there ...
The vocalist did thank my sax player friend for introducing me to her ...
