This is quite a fun thing to do when you have a spare half hour when lazing about on board.
Get a chilled bottle of champagne from the fridge.
Charge your glasses
Put your i pod on shuffle
Take turns to play and stop and you have to sing at least one verse of the song before you can re-charge your glass.
This means that the crew gets tipsy very quickly if they are good, or if you are like me end up with a very dry mouth!!
