A friend of a friend was at a wedding recently, and said that after dinner, a 'waiter' stood up and said that he was from the hotel, and that they had some comments about the wine, saying that it made people do strange things. He promptly tok a swig, and broke into spontaneous song!!
Then he walked around the room and pointed to a 'guest' who stood up and joined in. then a waitress started singing too.
Aparently it was really something different and wanted to get more info - anyone heard of anything like this? She said that they were called something like camouflage, but I have tried googling everything I can think of!!
I'n in Northern Ireland if that helps!
