Looks like the back end of a bus

This is not just any bus parked up outside City Hall, no this is a Beat the Street bus, a luxury coach for the entertainment industry complete with bunks, kitchens, every conceivable mod-con for the comfort and ease of the hard worked artistes. I think the artistes in question were a band known as Texas who come not from the USA but from Glasgow in the newly independent state of Bonnie Scotland.
