I don't have a clip (wish I did), but James Hetfield's (he of Metallica) kids went to my kids' school for several years (before they moved to Colorado). At the annual school fundraiser, he played an acoustic version of "In My Life" while a slide show of kids from the school flashed behind him. Then he auctioned off two signed guitars. It was pretty amazing.
One year he auctioned off a week of carpool rides each in a different automobile he owns. He was a really good guy -- very easy going, hung out with all the parents like a normal dad, except he's worth a quadrillion dollars and has more tattoos.
