I find it hard to classify ANY karaoke group... there's just too many variables. Some singers will favor one or the other, or even change as the level of intoxication happens!
For my own needs, I try to sculpt the audience to the way I host a show. If they like it, the gig works out. If not, it doesn't! I'm very open about that with the past venue owners and managers I've worked with. They want more of a DJ type show, they don't want me. I'm flexible, but won't change the way I host.
Now when I go out as a singer, I TRY to find shows like the way I run mine. Hard to do as someone ALWAYS has differences. You just have to figure out if they're worth biyatchin' about!
