Yes, so imagine just HOW talented "da men" like John Williams or Pepe Romero must be to be able to play Rodrigo's mind-boggling "Concierto de Aranjuez" from memory--WITH an orchestral accompaniament. I can't imagine the amount of time and practise it takes to memorize things like that! No wonder John & Pepe (and Dr.Frank from ECU) just close their eyes and never look at the audience--they need total concentration.--Mbo
