Actually, that is not OK. You are adding a floating point number to a
string. I intended there be no automatic conversion. Especially in
this case, since the writer apparently forgot the "&" before the "1.90".

Our shows are formidable
But many times
We're given rhymes
That are quite unsingable
We're opera mad in Camelot
We sing from the diaphragm a lot.
