There are 88 houses in Concertino City, but you only need to remember seven addresses: C, D, E, F, G, A, B (or H). Then you will easily find your way in Concertino. The first house C is the Concert School of Concertino. The next house D is the Disco. The third house is E where Emil is living.
She is living in the next house F, and they have great fun together because their houses have a big terrace on the roof with access from both houses E and F. Emil and Fanny like very much to meet there and rehearse before their concerts. They are concert artists, and lately they are rehearsing the EF song that they have composed together. They thought that the letters E and F look funny together. Don't you think so too?
