I have been a huge fan of Katy since Teenage dream album and I booked tickets to see her at Manchester last Tuesday . All I can is WOW. What a show. I wasn't expecting that if I was honest. The amount of energy she put in and colour and stunts were simply breath taking. My mate who came along isn't a big as a fan as me but went away saying it is one of the best concerts he has been to. Katy was note perfect for all songs and had a perfect mix of all the albums on the set list. Dark Horse was immense live and This is how we do sounded awesome live as well. For any true pop fan this is a must see concert. you will not be let down. I am even a bigger fan now and cant wait to see her again.
