I will admit it, without (much) shame. I was a fan of Hanson. I sang along with “MMMBop,” I had a crush on “the oldest one” (Issac), and I couldn’t get enough of that really goofy video. There are worse things you can do at 15.

Guess what? The guys are still cuties. And they’re working for a better world. The trio is now making their rounds on their Walk Around the World Tour, where they will promote their album The Walk as well fight poverty in Africa by raising money for healthcare, education and supplies.

The tour actually began last year, with a revolutionary concept: asking fans to walk a mile with them, barefoot, before each show, to represent the daily life of an African child. That’s pretty amazing.

But the event was put on hold when Issac had life-saving surgery for a pulmonary embolism. It’s officially back on this year, and from now until November 16 they’ll be continuing what they started.

The brothers have been AIDS and poverty activists for a while now, with various concerts dedicated solely to research and prevention as well as a partnership with TOMS shoes, where they company donated a pair of shoes to a child in Africa for every pair of shoes sold.

Incidentally, both Twice Shy & Toms were featured in our 2007 Green Celeb Gift List for their styles for little ones. Turns out we like the stuff for big kids, too!
