Thanks Orf. I took it to be one train snaking it’s way round the track. I prefer that to two single trains as they are all heading on the one train to the same Destination. Like the idea of a Sergeant pepper kinda idea with icons past and present in each window. Not sure about the legality though in using other people’s images. Even if there is not to be another album , it has been fun speculating about the cover. I wonder if Abba members ever read our comments?
