I know what Karaoke is and where it came from. What I’m wondering ia what is the Karaoke Circuit? I’ve only seen people, what the booze is flowing, pass around the Mic and go for it.
One can only assume that different clubs allow a traveling Karaoke setup to come to their establishments to provide that brand of entertainment. They don’t have the equipment themselves, nor do they offer Karaoke on a continual basis.
