It's very difficult to put it into words or really put your finger on exactly what it was that people found so attractive about Wham! But it was a lot to do with George and me and our friendship.

I had always been aware of George's importance to me, of the bond of friendship and of the sparkle and light, effervescence and electricity that suffused the music we made.

We were bringing Wham! to a close, but we weren't bringing our friendship to a close.

Despite the pain of his death, George is still very much alive in my memory today. A few years on from that tragic Christmas, I'll sometimes catch myself thinking of our friendship and those years together as young kids in Wham!

A loss of a great friend is traumatic and emotionally tough.

We were both dabbling with music but no, I persuaded George, railroaded him really into forming a band. I think we both had the belief that we would make it. That was the central pillar around everything else.
