Chameleon Circuit

It is returning through the dark
Doctor, you have met your mark
Your song is ending, sir, don’t cry
When you hear him knock four times
You’re going to regenerate
Some new man saunters away
No time for games, tonight we fight
For the fate of all mankind
I could do so much more
The time lords returning, the earth will be burning
The last white point star is a trap for the master
The doctor is dying
