"Thank you very much. This evening,
there is quite a program in store for you, 
we're going to be here for quite a while.
And, earlier today during rehearsals,
we had decided we had better put
all of the more strenuous pieces up front,
so that after we have keeled
over from exhaustion,
there would not be any great effort
needed for the end of the program.
Consequently, this next song
that we are about to do is
the most difficult song
that we have on the program this evening."
