Here are a couple of Hawkwind documentaries. You need to have at least two to get the full picture because the first documentary does not include founding member and only member to have been in (still is in) every incarnation of the bands turbulent history due to the fall out and legal action that other founding member Nick Turner took out against Brock to try and claim the Hawkwind brand name. Of course Brock won the court case because he is Hawkwind but he (Brock) refused to participate in the documentary such is the bad blood between the pair. So the second documentary I guess is Dave Bock's side of the Hawkwind story.
