Eurovision has a bus

Eurovision has a German bus. And it reminds me that I must book the trip to Azerbajan next year!
Who wants to come along? If you stop to think, you could ask if Eurovision has a German bus, or if Germany has a Eurovision bus.  Also, what happens to the bus next year? Does it stay as a Eurovision bus, or does it flip and become the "Steps on tour (Deutch Leg)" bus?
