we know that the sequel (or prequel) to Mamma Mia is coming out next year. But which Abba songs should be in it. Presumably they will use songs not featured in the first film although they may use one or two already featured. The two biggest hits not featured in the first film were Knowing Me Knowing You and Fernando. Im sure they may use KMKY but not sure about Fernando. So what others should be included. One OF Us, Angel Eyes, Day Before You Came and Summer night City are hits not included in the first film. How about album tracks like Eagle? Or if its set just after Christmas they could include Happy New Year!
