Cruise lines such as Carnival now offer live concerts by major artists on board certain sailings.  Attendees pay an extra fee to attend the performance.  For example, at Carnival Live performances, General Admission price is $40-$75.  VIP seats in the first four rows are $150-$250.  What do you think of having these concerts on board ships?  Are you for them or against them?  Would you pay to attend such a concert if you liked who was appearing?  Have you attended such a concert?
