Before becoming a teacher Donna performed with her band Hollywood Nites, and last year the group asked Donna to perform with them one last time.
Donna said: “When I started to put on weight I never thought I would sing again, but when my old band got in touch and asked me to stand in for one night I thought why not – and I haven’t left since.
“The outfits that I wear on stage are very revealing for a woman of my age, but I feel great and have so much more confidence now.
“I now weigh 10 stone and I wear a size eight on top and a size 10 on my bottom half, I don’t have to worry about covering myself up anymore or even whether I will fit into rides at the theme parks.
“Losing the weight has definitely made me feel young again.”
