The band's mix engineer, Snake Newton, spent all weekend putting the final touches to the audio for the Manchester show, "A Diamond in the Mind," which will be released as a stand-alone CD, as well as being part of a package with the DVD. The whole audio track was then mastered on March 5th at Metropolis in London.

Meanwhile, Gavin Elder and James Tonkin were also in "Diamond"-world, working on a final cut for the bonus documentary material that will go with the DVD. Telling the story of 2011, the band members talk candidly about the highs and lows of last year - from the loss of Simon's voice (which is documented with rehearsal footage) to how this catastrophic injury ended up bringing them even closer together.
