That's what Wolfgang revealed during a recent online interview with HardDrive Radio. Though the touching music video for "Distance," released last November, served as a postmortem tribute to the Van Halen guitarist, Wolfgang composed the number itself before Eddie's death.
Watch the interview down toward the bottom of this post. Wolfgang reveals that detail and more about Mammoth WVH's "Distance" to host Lou Brutus at about 7 minutes into the chat.
The 29-year-old musician says his father "had struggled a lot, health-wise, over the years. It'd be up, and it'd be down, and it was a tough thing to deal with. ['Distance'] was just kind of an expression of where I was in the moment, and imagining what … I would feel like without him in my life."
