Letra de Zurich is stained

I can't sing it strong enough:
that kind of strength i just don't have.
if you watch the lights change please
don't hold them hanging.
you think it's easy but you're wrong
i'm not 1/2 of the problem
zurich is stained and it's not my fault
just hold me back or let me run.
what does it mean a mistake or two?
if it's the kind of mistake no one can trace
to the fountain where we sold it
and held them hanging.
