So of course, there’s a bit of a problem with “Space Truckin'”. The studio version on Machine Head is good, but it feels unfinished, while the version on Made in Japan is far more powerful, but goes on for over 20 minutes.
And I’ve got to be somewhere in 20 minutes!
That said, even if you have warp drive, travel in space takes a very long time, so you need a song with a lot of long guitar and organ solos to accompany you. So the live version it is!!
