Two singers join the group half way through the show. They sing songs with lyrics which include the following:
Can we do it, Yes We Can.
Can we do it, You know we can.
Can we do it, Yes we can.
We all are one.

and

Do you give to the poor?
When ever I can afford.
Do you carry you brother's burdens?
When it is overload.
Do you take your neighbor's own?
I never did so.
Alright you qualify, So GO.
Which is I think a fairly good invitation to humanity.
