third and fourth verses above, minor corrections:
Look out of the window and over the roof there
Ove the wall see the sky
just one flying leap, and you could make your getaway
If only you could fly

The prison is sleeping, the night watch is keeping
His watch over 700 men
And behind every cell door, a sleeping lag is dreaming,
"Oh , to be free again!"

note- a 'lag' is a long-term prisoner
second verse - dreams are broken "on" those hard iron bars; 'oh' was probably a typo.
