What do you do when everyone else is singing along lustily and all appear to know the words and the tune of a song that is totally new to you?

Do you fake it - mouth the words and pretend that you know as well as everyone else?

Honestly try to join in and pick it up the best that you can?

Hang your head – shuffle your feet and wait until it is over?

Go to the toilet?

Noisily pretend to have a heart-attack or a fit of coughing - in order to sabotage the singing?

Or do you do something else?
