G.21. Musical Hat

With the group seated in a circle, a hat is passed (quickly) or thrown from hand to hand. At a given signal from the leader, whoever is holding the hat has to sing a song.
All sorts of additions to this game are possible.
If the group comes from a variety of countries they should sing one of their national songs; if they do not know each other well, they could choose to sing a song which they think describes their personality in some way.
After a verse (or a few lines only for the more shy participants) the whole group should join in the song – or learn it if it is unfamiliar to them.
After each song, the hat is rotated again.
