Job description: Karaoke hosts and what their job involves

This is a new one on me.

D.L.E.S. at Helium tells us that the karaoke host is a KJ not a DJ and that s/he has to be a motivator, a coach, a singer, an actor, a comedian, a dancer, a babysitter,and a radio personality in front of the public!

D.L.E.S. does not provide terms and conditions of employment for a KJ but my understanding is that most will be self-employed and will provide their own equipment. Return on investment, particularly the study time required to keep up with the latest trends in music, is likely to be poor but this may not deter the music lover who would be listening (perhaps with less purpose) to lots of different radio stations anyway.
Obviously there are not lots of openings for this type of work but could attract some young people who are not overly interested in a more academic or "tied down" existence.
