Now picking seats at a concert can be tricky. The seats at the back of an arena mean you watch it mostly on a big screen. Anything past the first ten rows on the floor level (unless it's standing only) means you end up standing anyway as those nearer the stage do. What you have to do is work out what blocks offer the best view and then hope for the best. The Echo Arena is not one of those who let you choose your own seats online.
So having bought seats in the right block we turned up halfway through the support act (plumber problems - don't ask!) who weren't my cup of tea but seemed to go down well. The photo below doesn't do the view justice.
