I'll fully admit, Willie Nelson is someone I came to appreciate as an adult. As I child I mostly knew him from his awkward duet with Julio Iglesias and just for being Willie Nelson. As a young adult I started to appreciate his music and I find that appreciation growing with each day.
I think because he's always been visible, it feels like he's family. Willie's like your cool, weird old stoner hippie uncle who talks a lot about booze, weed, hangovers and one-night stands.
Happy Birthday Uncle Willie!
