Ok these are the rules.
I start by picking an opening line to a song. The next player in turn ads a line from a completely different song to the new song we are creating. The new song has to make some sembalence of sense (I know that is a tough proposition on this forum.) Once a line is taken from a song, that song may not be used again by another player. The final song will be composed of 4 stanzas of 4 lines each. The person to write the last line of the last stanza starts the next song.
My first line is
"Now I've had the time of my life"
