Ooh, now that I didn't know.
I may have to see if any kind soul has bunged the second version on youtube.

Which is the favoured version?
And what album was it on?

One has Lemmy singing, the other Dave Brock.

Oh, hang on,
I do have a second version with Brock on vocals, which I think was recorded live (it sounds a lot more rough and there's no sax or violin) - is that the one you meant, or is there a second studio cut?

I cannot remember. I may have to double check
I recall (perhaps wrongly) that the version on my Motorhead 4-LP compilation (which has a Hawkwind version) is different from my 12".
