Always remember that fear is your friend. The adrenaline you will produce has two possible effects; 'fight' (ie performing well) or 'flight' (ie running away). You can decide which effect will predominate. As a performer, the time to get really worried is when you don't feel nervous; generally speaking that means the 'edge' has gone. One little tip; adrenalin also causes dryness in the mouth. The traditional folkie remedy for this is beer, but sucking a mint before you go on works too! Break a leg.
