A new offer has been announced on Pink Floyd's official website: if you have purchased any version of The Dark Side Of The Moon on CD or if you purchased the 2011 remaster at iTunes or on vinyl, you can now unlock a free download of Money (Roger Waters Demo) – previously only available in the Immersion Box Set.

To access the bonus area, visit www.pinkfloyd.com/bonus and follow the on-screen instructions. You'll either need to insert the CD (and it can be any official version that has been released over the years), go to iTunes if you downloaded it, or, if you are an owner of the 2011 vinyl, there was a paper insert with a code on it...
