Missing PF Relics tracks

[VAXman(Admin)]

I was just reading a new post to the "new shows" thread and thinking about the Headphone Only
show. I can remember hearing Bike played on the old Philly For Headphones Only show and it
made me wonder if Bike was here on the moon.

Relics is a collection of early Pink Floyd. Some of its tracks are listed here from the original albums.
A few tracks exists from Relics itself. Four tracks: Arnold Layne, Bike, Remember A Day, and The
Nile Song that exist on Relics are not on the moon.

Are these an oversight in the shuffle with tracks from other albums?
