It's Trock. Maybe Torchwood Rock?
lyrics
Daleks [bad word] me down and Rose brought me back around 
my time has greatly slowed and when I'll die I don't know 
If I even can I am an immortal man 
I've lived so many lives [bad word] back a thousand times 

I'll never die living on my past my time 
for thousands millions maybe more years I have left to go 
I'll always be here and I will always care 
No matter where my path may go, I'll never die 

The doctor left me not quite sure what I would be 
I traveled back to Earth just trying to find some answers 
Rebooted Torchwood to do the best that I could 
making sure that the rifts protection can not be lifted 

I am Captain Jack, I am the Face of Boe 
You do not know my past, I'd bet you'd like to know 

I'll never die living on my past my time 
for thousands millions maybe more years I have left to go 
I'll always be here and I will always care 
No matter where my path may go, (woah) I'll never die 

Same can't be said for my friends 
Owen Tosh and Yanto gone 
the ones that do not die 
grow old in front of my eyes 
generations will pass 
and will i [bad word] the last 
outlive reality 
billions of years i could see 
taking one day at a time 
and I know I'll be fine 
well I think I'll be fine 
oh god I hope I'll be fine 
Fighting for what is right 
for the rest of my life 
for my life for my life for my life 

I'll never die living on my past my time 
for thousands millions maybe more years I have left to go 
I'll always be here and I will always care 
No matter where my path may go, (Woah) 

I'll never die living on my past my time 
for thousands millions maybe more years I have left to go 
I'll always be here and I will always care 
No matter where my path may go, I'll never die
