"Had an amazing time last night at the Sabbath show", Wolfgang posted on instagram, along with a photo of the three Van Halens hanging with Sabbath guitarist Tony Iommi backstage. The bassist also posted an instagram photo from the concert, writing, "Wow. #Sabbath was f***ing mind-blowing tonight."

Long before Wolfgang was born (in 1991), Van Halen opened for Black Sabbath on their 1978 tour; VH were on the road in support of their groundbreaking self-titled debut and Sabbath were supporting their "Never Say Die!" release and 10th anniversary.
