It promises to be over a 2 hour show, and back to an end of stadium stage after the "in the round" 5 month American stint. Starting in Newcastle 25th June, Manchester 28th, Twickenham 30th, Ipswich 3rd July Glasgow 5th, Cardiff 7th and Coventry 9th july. Dublin x2 after that. Its a stadium tour, and you could grab a cheapo ticket on ebay, theres lots of them on there, or take a punt on the day, I certainly wouldnt pay full price when theres a bargain to be had, and if youre only interested in a night out and a bit of curiosity, then either on ebay or outside on the day is the way forward. Get along, its a good show.
From what observed from the US Arena shows is that he did not interact much with the audience. Sure there were 180 degree catwalks on 2 sides, but only used them a handful of times.
Most of the show was Rod singing on an elevated riser in the center of the stage like he was on the top of a Wedding cake.
Like Dishevelment says, the "in the round" stage is history for the UK. Never seen a decent in the round show yet. So Rod will be back in the UK, with front facing stage and he always puts on a good show. You won't be disappointed. Get yourself to Hampden, then if you want interacting you'll get shed loads of it.
I've got one Rod Stewart album - his debut album, and I love it. It has for example a great version of Street Fighting Man, and the excellent Blind Prayer (inspired by JJF?).
