We went to Duelling Pianos on our cruise starting 09/22/01, the first 7-day-cruise after 9-11 and it was so great!!! The last half hour our the musicians played the American Anthem, You're a Grand Old Flag, America the Beautiful, etc. and it was so pathetic - Especially for us Germans as in our country openly displayed patriotism ist still frowned upon due to the dreadful part of our history from 1933-1945.
We're looking forward to see -and participate in - the show again on our next cruise.
