He was on a plane to New York when the 27-year-old’s death was confirmed. The budding singer, who released his debut album in April, had been due to perform at the Blue Note jazz club in the city, but cancelled the performance and caught the first flight back to London.
Last night Mitch was seen in the first class lounge at JFK Airport, pacing and talking into his mobile phone. He reportedly told the Sunday Mirror: "This isn't real. I'm completely devastated. I'm coming home. I have to be with Amy. I can't crack up for her sake. My family need me. I'm devastated, it's such a shock."
A member of Amy's backing band The Dap-Kings, saxophonist Neal Sugarman, has spoken to BBC about his happy memories of the star, before her decline into drug addiction.
"She was a great musician and really open. She was really into collaborating with the band and never came off as being bull-headed in any way," he said of their time in the studio recording the Back To Black album.
"Unfortunately the last time I saw her, which was a little while ago in London, it was not a pretty sight,” he continued. “It was real depressing. We cut something that she wasn't able to sing on, which was a real drag.
"Everyone loved looking at the tabloids but everyone was hoping that she would make a comeback."
