I was going to say Avril as well - went with a friend with a spare ticket.
It blew my mind to be honest - never been to a pop arena show and the noise from the crowd was deafening - i’m sure that was where my tinitus came from and not 25 years of pub gigs.
Other than that i remember going for a pint about 9:15 and the bar was shut, so went for a smoke and got chatting to a heavily tattooed/pierced bloke bloke older than me and asked who he was here with - daughter perhaps and he told me he was here on his own to see her as she’s fucking amazing. Never judge a book…
Still, complicated was a banger
