Gravity

This is based somthing still to come in my fanfic. I'm not bothering rateing it as a spoiler as, apart from me, no one will get what part its from.

Lyrics:

been a long road to follow
been there and gone tomorrow
without saying goodbye to yesterday
are the memories I hold still valid?
or have the tears deluded them?

maybe this time tomorrow
the rain will cease to follow
and the mist will fade into one more today
something somewhere out there keeps calling

am I going home?
will I hear someone singing solace to the silent moon?

zero gravity what's it like?
am I alone?
is somebody there beyond these heavy aching feet
still the road keeps on telling me to go on

something is pulling me
I feel the gravity of it all
