George Michael is busy putting the finishing touches to his special documentary film ‘Freedom’. He has discovered some incredible, unseen archive footage and is shooting additional interviews for the project so the film will now air in March 2017. It promises to be a real treat for fans! To coincide with the film’s broadcast, George and Sony Music have decided to move the reissue of the Listen Without Prejudice album to the same time.

Former Wham! singer and solo superstar George Michael has died. He was 53. Though no cause of death was revealed, his publicist said he "passed away peacefully at home." Michael sold more than 100 million albums in his lifetime, bridging teenybopper pop and R&B both with Wham!, a duo that also featured singer Andrew Ridgeley, and as a solo artist.
