A: Sing a song you know upside down, inside out and backwards. A song you don't need the screen for... so instead of reading words off a screen, you can make eye contact with the room. Nobody knows how you feel on the inside except for you, so just pretend you are very comfortable and people will believe it. That is why it is so very important that you know the song very well. If you get nervous, and have to read from the screen the entire time, you will miss the real thrill of performing a song, and nobody really came out to watch you read your lines from a monitor. Connect with your audience, pretend you are not afraid of them. Make yourself stand out from the countless nameless faces that proceed you, by connecting with your audience and putting on a show for them.
