This is not so much a Finale issue as it is an "accepted practice" ques ion.  Would like composers' opinions.  The original commissioning contract on a choral piece specified middle school voices with piano and optional other instruments, and a "commissioned by" credit to the middle school and director.  Now, a different party has requested an arrangement of this piece for men's chorus.  The new arrangement required more than a mere key change. Notes and rhythms in some of the voice parts are markedly changed in the last third of the piece, and the instrumental parts are completely different in some sections to accommodate the difference in voicing.  I am thinking that the original  "commissioned by" credit is no longer appropriate, as this version is obviously not suited for middle school. The contract doesn't require me to include a commission credit for other versions, but I could still include a credit that reads, "Original middle school version commissioned by..."  Is there a common practice in these kinds of situations?
