Can we get the rules first please? From the OP I don't think it's just getting the singer or author. In the opening example the 'answer' is the second half of a verse - hence, I guess, the name 'couplets'. There are extra points for author etc.

Don't think you'd be able to 'market' the game as couplets though. Stricly speaking a couplet is two lines and the opening example is a quatrain. If anyone is remotely interested it is a quatrain on the AABB model! How about a nice pedantic title like 'I'll give you the first half of a verse and you give me the second half. Extra points for singer and author..' Just slips of the tougue doesn't it:-D

Enjoy it anyway
