Portastatic - Guessing lyrics

I know There's a whistle before it blows And I know There's a ticking until you go And I wish This was written down somewhere I guess That would not be fair I'm guessing from now on I'm guessing from now on I know You will string up lights Flashing through the night They are spelling out what you want me to know That you're hiding something And I won't go I'm guessing from now on I'm guessing from now on
