Polly, yes, a signed up member or members can then do "anything" with the song. (key, style, tempo, arrangement). Think of the covers that were not like the original. All it's own. That would be interesting than to try to copy the original in every way. Make it YOURS, (and with whoever JPF member).

Looking forward to hearing yours,
John
