[Schizoid Man[_2_]]

I'm watching the Director's Cut DVD of Live at Pompeii and have noticed
something a little odd.

This film was allegedly made in 1972. Why then are the words 'Shine On'
clearly scrawled across the Abbey Road NW8 road sign (incidentally just
200 yards away from my apartment) at the end of Echoes Part I?

Considering that WYWH was not due for another 3 years, is this:
- an uncanny coincidence
- the basis for the WYWH song
- proof that time travel is possible

Thanks,
Schiz
