More on the song-chain game:

As I envision the game, the rendition doesn't have to be all that great, nor does it HAVE to be accompanied, but the singer should definitely be able to come up with something related that he/she can sing a full song of, however raggedly, however out of tempo, etc.

A possibility that just now occurs to me is is that if a singer is disqualified,one of his/her two tries failing for not being able to come up with the full song, the next singer may sing that whole song as his/her offering.

I didn't mention, but it should be clear that a singer may, if stumped, confess being stumped and accept disqualification.
