Let me continue...
You hire a sidekick to handle A/V. He/she takes live shots of the hot bods on the beach dancing and vogueing. You post up quick pics of those sitting around. Your sidekick uploads pics from customers' wallets. You have your own slide shows that are sync'd to your music, like part of the registration setting. Everybody has a great time watching the 52" screen and dancing under the flashing LED lights. As it gets darker and the mood lightens up, you switch from playing arranger/SMF type music to songs with the lyrics on the screen. The crowd watches you perform. Your guy takes more live action shots of the crowd singing along, having the time of their lives because they're part of the entertainment too.
You pump up the volume, sing another song with the lyrics up on the screen and ask that beautiful woman dancing next to the stage to come up and sing with you. BAM! Now the crowd's into it. Her boyfriend wants to sing a love song. Bring him on stage and voile, karaoke - and YOU'RE in control. Play the damn song yourself, the words will follow your lead.
The amazing part of all of this is you are controlling the music, the mix , the audio and video all from your keyboard. If you want to play, then play. If you want to watch, watch.
And you think Roland is crazy? Crazy like a fox! This is cutting edge stuff. If they don't advance this concept, you'll see some other Asian corporation take the ball and turn this into the next entertainment phenomenon. Meanwhile, the old fashioned DJs will be sulking out in the cold along with the "musicians."
