Brothers Isaac, Taylor and Zac, as the boy band Hanson, shot to fame in 1997 with pop classic Mmm Bop. Now at the grand old ages of 19, 22 and 24 respectively, they’re back in the charts.

They talked to Sky about how that single changed their young lives, how Mmm Bop is one of Bono’s favourite songs, and how they’re getting on as adult musicians.
