Let me introduce you to Hanson.
They're three brothers in a band called Hanson, not so strangely also their last name.
Hanson, the band, has been around since 1995 or so, and released their major-label debut in May of 1997. It was poppy, exuberant, and completely different from what else was on the music scene at the time. Their hit single, MMMBop, was at the sametime annoying, catchy, joyful, and well-written. I loved it.
The members of Hanson don't have long hair anymore. They are well past pubesence, though that's what they're remembered for. They're family men who love music and pretty much everything that goes with it, from instruments to gear to the latest media trend.
They also grow some unsightly facial hair.
