Off the Grid

My sentence is end like this
 By hacking and digging with the spoon and a shiv
 Tunneling inch by inch
 My strategy hinges on the fact you've missed
 Too long coming locked down I'm breaking out
 Oh oh so long
 Served my days, but now its coming round
 Oh oh so long
 Confinement gives birth to reflections
 I wish I could trade ill-fated decisions
 My penance has earned these offences
 I'm crawling my way to independence
 Too long coming locked down I'm breaking out
 Oh oh so long
 Served my days, but now its coming round
 Oh oh so long
 (Background voices)
 Wait for moonlight
 Time for searchlights
 Lay in the shadows
 Preparing for flight
 Wait for moonlight
 Time for searchlights
 Lay and prepare for flight
 My captors convinced that I'm pinned
 Down in dependence on the system that fostered
 An institution of thieves
 But I live to see
 The shock in the faces when my cell is empty
 Too long coming locked down I'm breaking out
 Oh oh so long
 Served my days, but now its coming round
 Oh oh so long
 Too long coming locked down I'm breaking out
 Oh oh so long
 Served my days, but now its coming round
 Oh oh so long
 Oh oh so long
