The subject of last minute singers is one that kind of has to be handled carefully for fairness.

Personal policy, new singers are no different than singers at the start of the night. When the night begins, people go in to the rotation in the order they come up. As the night progresses, new singers go at the end of the rotation. No exceptions.

If someone does the "Aw, c'mon, I just camer in to do a quick one then I'm outta here." Politely explain that it wouldn't be fair to the people who have been waiting a while to sing, but if he/she would like you can put them in the rotation at the appropriate spot. (Appropriate spot being a polite way of saying at the end of the line as has been hapening with new singers the whole night)
