I was thinking about that, and exactly how I would teach the chorus to an audience, and encourage them to join in.

It's a relatively long, complex, chorus. And most of it is specific to my (or any disabled singer's) P.O.V. However, 'Cause I am simply human, in this complex human race is universal to everybody in the room.

So I think that is the one line I would recite for them, as I start, and encourage them to join in, rousingly, on the chorus. Perhaps using that one line, with a variation on the melody, as a coda to the song?
