There is no telling what one may see when they dream at night, and classic rockmusic icon Sammy Hagar discovered this when a night's sleep inspired his brand-new song "Encore, Thank You, Goodnight."Over the course of his career, Hagar has been known for creating classic tunes. He emerged at a time when he was competing against the likes of AC/DC, Guns N' Roses, and Ozzy Osbourne, yet he managed to make his name one of the most relevant in music. This includes both his work as a solo artist and in bands.
