The Great Unknown lyrics

Finally we are on our way Where no man's gone, launching deep into the great unknown Space and time passing by, but the world outside is swallowed whole by the starless sky I turned the key in the door It's been a long time a-coming I've been a long time gone I can't believe this is happening to me We have passed the sun and something tells me this has just begun I turned the key in the door It's been a long time a-coming I've been a long time gone All the forces of the cosmos lead me on as we shoot through the galaxy I'm coming home!
