When it comes to music, the 90s gave us a lot of gems, but none of them has defined an era as much as 'MMMBop' did. Everyone who's lived through the 90s knows exactly where that quasi-gibberish word came from and has definitely sung along to it. The band behind the hit song, Hanson, was formed in 1992, but it wasn't until they dropped their debut single in 1996 that they became worldwide sensations. Composed of brothers Isaac, Taylor and Zac, Hanson went on to sell over 16 million records worldwide and steal even more teenage hearts along the way.
