Then, there is the Dean Martin version:
Goodbye, goodbye to Rome
City of a million moon lit faces
City of a million warm embraces
Where I found the one of all the faces
Far from home
** I will continue to be near to you in prayer, especially in the upcoming days, so that you may be entirely docile to the action of the Holy Spirit in the election of a new Pope. May the Lord show you what He wants you to do. And among you, in the College of Cardinals, there is the future Pope, to whom I, already, promise my unconditioned reverence and obedience. [The fact that he says this here and now means that he is not going to appear later to do it in public. He really will just disappear and cast no shadow hear the new Pope.] For this, with affection and thanksgiving, I impart to you from my heart the Apostolic Blessing.**
May the Holy Spirit, indeed, guide the Cardinals as they select a new Pope.
Not today. it was adios and that changes the song quite a bit.
