My singers give me the name (title) of the song or the name of the artist, NO NUMBERS!
I started hosting karaoke with disc and CDG player using numbers like everybody else and understand that old habits can be hard to break but a paperless show means less work for the KJ. This alows the KJ to focus on the singers and the show. It takes a little while to train your singers but once they get used it they will never have to remember a number or write on a piece of paper again.
Paperless/Numberless Shows, The only way to KJ!
