Lockman,
The proceedure you use is exactly what my wife and I do at our gigs, but let me tell you what we do that is a little different and has an impact you won't believe.
We have taken the singers returned requests and printed them individually on a fresh request slip, singer's name, song title and track number. Now you can read the request slip and know that all the entries are correct. Next the singers stack of printed requests slips are put into a 4x5 inch clear plastic zip lock bag. On the outside of the bag we have placed a small address label with the singer's name on the label. The plastic bag makes for easy storage, indexing and retrevial by my wife and for handing out at the next gig. The plastic bag helps to keep water, beer and soda etc. off of the slips while the singer has them at their table. This proceedure is only done for our "regulars".
Here is the effect this has had. The first night we did this, our regulars lit up like a Christmas tree. Now on each gig night you can almost see our regulars strut up to the KJ desk to get "their own" special package. There isn't a night that goes by that a non-regular singer will come up to the desk and ask "How do I get my request slips printed up like those other people?" Our response is, become a regular at our show and we will put a package together for you. Many will say that same night, I'll be one of your regulars, and they do come back.
Just this little added extra has made our regulars feel special, not just another karaoke singer. It has also brought in new singers who quickly become a regular. You might want to give it a try. It's a little work initially, but once it's in place it's easy to maintain (if you have a wife who is handy with a computer and can type
).
