ZZ Top's Dusty Hill remembered by 'Duck Dynasty' star Willie Robertson: 'Our beards bowed down' to him

"Duck Dynasty" star Willie Robertson had come to meet the founding member of the blues band when its song "Sharp Dressed Man" became the theme song to the rowdy family’s reality empire.

On Thursday, Robertson told Fox News that news of Hill’s passing brought back memories of the last time he and Hill had seen each other – just two years ago at the band’s 50th-anniversary shindig, which doubled as Hill’s 70th birthday party. "We shared with them something similar in that we kind of came from generally the same area and kind of came out of nowhere. We just do what we love to do." "Our beards bowed down when we got in their presence because they had been running that look way longer than we had, that's for sure," Robertson said of the signature moment. "When I was with them a couple of years ago, they were heading off to Europe to play for like two months or something, it was crazy. And I was thinking at the time, not a lot of people have their 70th birthday and then take off to Europe to keep working and keep doing what they love to do," Robertson continued. "And it's just a tribute to him and their lives, their passion and what they had. They had something good and they kept it together, kept the look, kept everything."
