The Emcee's Handbook for Excellence
#7	Rehearse your introductions and other remarks.
It is commonly expected that performers and speakers will be prepared and rehearsed. The master (or mistress) of ceremonies should also exhibit that high level of preparation. Prepare all remarks that you plan to make. Familiarize yourself with all introductions and biographies. Practice reading them so that your presentations will flow naturally. One sign of excellence is being rehearsed without sounding rehearsed.
