Did He Ever Go Away?

OK, this is another thing I don't really understand but I'm prepared to let it go. I won't be attending the concert - I think 62 euro is a wee bit steep but maybe that's me just being a tad mean.

If you do go, I do hope you enjoy it.

This was the last photo of today and replaced what I thought was going to be a cast-iron certainty of a blip - a very odd bit of graffiti that read "Beam Me Up, Nobbi!" I can only guess as to what was going on there.
