playing outside does pose a whole new playing situation. By all means, play outisde fist to see how different things are. Especailly important, avoid direct sunlingt or even highly lighed areas. The screen on the keyboard as well as button lights,etc, may be difficult if not impossible to see. Always have an emergency plan in case of sudden rain. You may need an extension cord and surge supressor, all 3 wire grounded. Clips to hold music down and in place in any breeze. Another goood song for this wedding - MY BEST TO YOU MAY YOUR DREAMS COME TRUE, TRUE LOVE and perhaps, THE SECOND TIME AROUND. Good luck.
