An audience member is asked to participate in a game where they must start singing when watching one of two players, with their biographical facts incorporated into the song.
The moderator asks an audience member to enter the stage. This person may sit on a chair. Some biographical data such as name, hobby, favourite activity, occupation etc. are requested from the audience member.
Two players sing to the audience. One on the left, one on the right. The person who is watching the audience member must start singing (this has been told the audience member before). The known biographical facts are also included. Whenever the audience member changes his or her line of vision (looks to another player), the singer changes immediately within the song (and the other player starts singing).
