On the other hand, Dave, if it's "three songs or 10 minutes," a performer shouldn't have to quit after 3 minutes if s/he wants to throw in 3 "quickies" (e.g., the Smothers Brothers' versions of "Hangman," "Blood On The Saddle," and "Streets Of Laredo"). Personally, I prefer to have a time slot specified and have the emcee give a finger signal when I have, say, 3 min. left. [As long as they don't signal you that way when you have ONE minute left. ;) ] Some judgment is called for, of course. If you finish a song at the ninth minute, you don't do another one unless you can finish it in about 30 sec.
