Hi Brian I do not think the main purpose for the exercise is necessarily to do well on Ourstage. IMO the Ourstage judging is inconsistent and fickle anyway.

I see it more as a challenge for us all to try something new and novel, help us to develop skills, explore new partnerships, give a JPF member a chance to see their own original song treated in different ways. Ourstage is just the vehicle we would use to place the finished results.
Most JPFs would not under normal circumstances have a song treated this way. It is a learning curve for us all.
Giving it to already established people or well known songs would IMO defeat the whole purpose of this fun exercise. Any Ourstage success although welcome would be an extra bonus.
