"I’m from Iceland originally," he explained. "I moved to the UK and friends of mine told me I wouldn’t be able to hold a conversation in the UK unless I knew something about football!
"They took me to Spurs and taught me the ropes. It was a new love for me.
"The first match I saw here was a 0-0 draw against Manchester City in 2010. Joe Hart was incredible against us. It was an incredibly emotional game and dragged me in.
"Up to that moment, I couldn’t really care less about football. From there, I was Spurs for life."
One of the most popular bands around, The Vaccines have released three albums to date - 'What Did You Expect from the Vaccines?' (2011) and 'Come of Age' (2012), which charted at number one upon its release.
They have also toured extensively and supported huge bands like The Rolling Stones, Arcade Fire, The Stone Roses, Arctic Monkeys, Red Hot Chili Peppers and Muse.
His advice for budding rock stars? Simple. "Work hard."
He continued: "You need a bit of luck as well, but if you don’t work hard you won’t be in position to get that luck."
