In case you missed this performance of Mmmbop by Hanson, 20 years after the song came out, here it is.  Their voices are deeper of course, but I think that makes the harmonies even better.  Hanson has gone from boy band to just band!

For comparison (and for the purists out there), here's the original song.  It's still a great tune-- always fun to hear.  Have a great weekend! ~Brian
