The Wanted are the first British boy band to reach the top 10 in the U.S. since Take That had a no.7 hit with Back For Good in 1995.

However, further Stateside hits have alluded Take That since.

Meanwhile, their younger counterparts One Direction, who were formed on X Factor 2010, are the highest British new entry on the U.S. singles chart since The Verve’s Bittersweet Symphony.
