Mark was the most amazing, genuine, humble and loving guy I have ever come across. I can’t believe he has gone it breaks my heart so much. It doesn’t feel real he’s not here anymore. Rest easy M may the angels look after you now I just wish you let us look after you you are missed so much already mark the world is crying for you thank you for being the kindest soul I’ve ever met I’m so grateful to be able to say I was lucky and met you so did my son when he was 2 months old He will be told all about you we will NEVER forget you mark 💔 “Big Love” 👊🏻

Mark was more than just an artist, he was a big brother i looked up to, a friend that i could trust. He was always there to give us motivation when we needed the most, he listened us with an open heart and always approached us with kindness and caring. Although i still struggle to fully grasp the situation and accept that he is gone, i know he doesn’t want us to remember him with tears but live our lives to fullest and cherish his spirit along the way. He encouraged me to follow my dreams and become a doctor. As i am graduating in less than a few months, i will dedicate this achievement to him and heal my patients with the power he and the script gave me. Because without them i wouldnt be here, as cliche as it sounds, its true. I will miss you Mark but i will keep my head up and live for you. Rest well my superhero

Mark was a real inspiration to me. We shared a lot on Instagram, he advised me on my first guitar, gave me tutorials and showed me the equipment he used. He was a generous man and artist, who listened to his fans, and was interested in our lives. He promised me a guitar pick after the London show in 2022, and he kept his word. I will never forget him and he will always be my guiding star. Thanks for everything Mark, and all thoughts for Danny, Glen, the script crew and Mark's family
