Keen singer Jordan, who's 28, hopes his version of Calum Scott's You Are The Reason, which is now on YouTube, will raise money for the Motor Neurone Disease Association as well as raising awareness about the condition.
Jordan, who's worked at the store for three years and who lives in Oldbury, said: "My mom loved hearing me sing, whether it was at weddings or on the karaoke, so I promised her I'd so something to raise awareness. It's a terrible disease with no cure.
"My mom was a woman who loved life, and who lived it to the fullest. She took every opportunity she could, ran with the wind, and made sure that every second of her life, and the lives of those in her company, was the best it could be.
"She was the sunshine that shone down from the sky, through the clouds on a rainy day but the day before Mother's Day this year, my beautiful mother was taken away from all of us due to the horrific disease that is Motor Neurone Disease.
"After a life expectancy given to her of between three to five years, it only took six months for this cruel disease to take my mother away."
"Mom's one wish was that other people did not have to suffer the way she did, trapped inside her own body, unable to truly be alive. Consumed by the paralysing effects of the disease, with no treatment or cure available, she prayed, she wished, she hoped for something to change."
Annmarie was married to Martin and lived in Upton-on-Severn.
Jordan said: "We do not want anyone to suffer the way Mom did. We do not want anyone to lose their dignity and with the support of some incredible colleagues, friends and family we can change things."
Jordan, who's engaged to Samantha Halliday and has two children, Oliver, six, and Grace, three, said: "Everyone at the store has been so supportive, especially our store manager John Perry. I can't thank him enough."
John said: "All of us at Asda Queslett are so proud of Jordan and we all support him. His song in memory of his mum is so special, so please listen to it and give generously to the Motor Neurone Disease Association."
