Spandau Ballet are back together, even Bros are rumoured to be thinking about it. It is an age of re-formation.
There remains one glaring exception, of course, and their name is Abba. For too long the former members of this band have ignored the demands of their old fans and a new generation turned on to their music by its endless appearances on wedding playlists and latterly, by the film Mamma Mia!
Their fans demand another tour!
