"A Million Cars" isn't on Sideways?
AFAIK, the only version of this released so far is the one on From Trash. Wonder if you're confuring this with "Impossible"?
Even then - the versions on From Trash are not 'edited' are they, which is why they are described as extended on Sideways.
Similarly "Freeze frame" on The Hidden Man.
I'm not aware of 'edited' versions of these tracks?
Is there any difference between the versions of 'From Trash' on the album, and that on The Hidden Man?
Unless, I'm missing something obvious. More coffee, please
