Pretty basic idea that came to me on the train.
Take a song and turn it into an email/letter, and see if the next poster can guess which song the email is adapted from.
For example:
Mother,
It’s me, writing from the road. Had a rough night tonight; apparently I had a little too much “fun” before the show and ended up passing out. Next thing I know, my manager (have I ever mentioned how much like Bob Hoskins he looks?) is standing over me and someone was jabbing me in the arm with a four foot long needle. It was a hell of a pin prick, but afterwards I was feeling pretty damn comfortable, and was able to go on with the show. Reminded me a lot of the time I was a little kid, and had a really high fever. My hands were all swollen up (kinda like two balloons, you know?) It’s kind of hard to explain, you probably wouldn’t understand anyway.
Much love,
P
