What's this I hear about some karaoke nights where the vj's talk crap about the performers. I know some singing should never be sung, but most karaoke nights are all about having fun. As hosts, they should be making everyone feel welcome.
To add, what's this I hear about some karaoke nights where the other singers are so critical and judgmental of everyone, like it's a competition.
I also heard of a strip karaoke night where singers can sing a song while a stripper dances. Sounds frightening, but I would choose "Nothing Compares to You" by Sinead Oconnor as my song.
