After more than 60 performances throughout Slovenia, <em>Mamma Mia!</em> returns to Križanke in Ljubljana, where this popular musical from London’s West End received its Slovene premiere two years ago. The action takes place on a Greek island and presents a romantic story full of optimism and vital energy. The musical is packed with hits by Swedish superstars ABBA, through which we get to know Donna, an independent-minded single mother who doesn’t need a man to feel fulfilled, and her 20-year-old daughter Sophie, who dreams of romance, babies and a fairy-tale wedding.
