Sammy Hagar revealed that his new single includes a guitar lick that his former Van Halen bandmate, Eddie Van Halen, showed him in a dream. The musician spoke about the song's origins in an interview with Ultimate Classic Rock while he was writing the song. "About two months ago, I had this dream and Eddie came," he said. "He's going, 'Man, let's write some music!' I said, 'Yeah, f**k it, man. Here, let's go!'" He went on to explain that in the dream, Van Halen "did this harmonic thing and he slid it up to a chord, like a slide guitar. We wrote a song with that lick," Hagar continued. "I remembered it. I got up in the morning and I wrote the song. I used the f**kin' lick that he showed me in the song." Van Halen passed away in 2020 at the age of 65 following a battle with cancer, and Hagar later revealed the two had patched up their relationship before his death. Hagar's new track, Encore, Thank You, Goodnight, drops today.
