Before music took over his life, Donnie studied at Gray's School of Art in Aberdeen and became an art teacher, and he painted the wall as a favour to his son Niall, whose café, Birch, looks straight across at it.
He toured the island taking photographs on his phone for reference, then sketched the scene, and friends who do projections for Niall's SkyeLive festival threw the sketch onto the wall so he could paint it. The work took four days, with a steady stream of passers-by stopping to talk to him as he went. The mural is on the street and can be seen at any time, and the café across the road is the obvious place to sit and look at it. Donnie, his son says, now has free coffee for life.
