My uncle recently worked with Dave Grohl. I met him at a party in 2009 right when they became friendly. He's a really nice guy, and kept complimenting my tattoos. I held it in the whole party but as we were leaving I had to tell him that Nirvana pretty much influenced my life for good in high school. He smiled and said thank you. I thought that was cool. I should have said thank you, but he had the humility to say it to me.
Here's my uncle's band website. The last picture in the slideshow is him and Dave signing at one of their shows:

Adam Sandler's wife and kids were also at the party. His wife is really nice and thanked me for occupying all the kids. I was just trying to make my cousin laugh, I had no idea that I was also playing with Adam Sandler's kids too!
