In india,we play a game called 'Antakshari'. ( A song starts with the last letter of earlier song). It just goes on and on.

The game will be-

Devide the whole group into two teams

Team A will sing a song or couple of lines of a song.(one member or whole team will sing)

Team B will pick the last word or letter of the song and start a new one..

You can have rapid fire section, you can give them a word and asking them to sing a song ,so the word should come somewhere in the song..etc.

I tried my level best to explain it to you..
