The New Radicals reunite tonight.

As Ashley Biden wrote in her dad's book, when her brother Beau was battling cancer "During breakfast, he would often make me listen to what I thought was his theme song: 'You Get What You Give'" by the band:

2/ Ashley writes in "Promise Me, Dad," that even though her brother "never stopped fighting and his will to live was stronger than most," she thinks he knew he wouldn't survive.

3/ "The words to the song are:

'This whole damn world could fall apart.
You'll be ok, follow your heart.
You're in harm's way, I'm right behind'...

4/ "In retrospect, I think Beau played that song during our mornings together-- not for him but for me. To remember to not give up or let sadness consume me, consume us."

Anyway, that's why the New Radicals are reuniting tonight.
