Anyone know if there are any plans to release this on DVD?
Why has it not been released yet?

It is easily available on Ebay as a bootleg. Quality and price vary, so exercise discretion.
BTW, to anyone thinking of buying a copy of 'Cocksucker blues', I waited years to see this before buying a copy from Ebay. It is nothing less than a cheap porn movie with a couple of badly recorded Stones concert performances, very dissapointing.

I dont want to buy a bootleg because of the inferior quality.

I presume there may be copyright problems re an official release?

I remember reading an aricle in Mojo or Uncut last year where a release was hinted at. I know the rights to a lot of Beatles material is still affected by their involvement with Alan Klein.
