Hanson 'MMMBop's Back Into Our Hearts on 'Dancing with the Stars' (VIDEO)

This week's house band on 'Dancing with the Stars' (Mon., 8PM ET on ABC) had the network reaching into the way-back machine to 1997. There they found the brothers Hanson, and the pop trio treated 'Dancing' fans with their biggest hit, 'MMMBop.'

While the boys were but tweens and teens when the song took them to number one, they're now aged 25-30. Nevertheless, they looked and sounded as youthful as we remember while clearly having fun playing with the 'DWTS' dancers performing in front of them.

On a night of "Guilty Pleasures" we could all take a moment and remember the t-shirts we had, and the well-worn cassingle we listened to so much the lettering on the outside had faded as fast as a ... well, an mmmbop.

What did you think of Hanson's signature performance?
