Sammy Hagar Shows His Colors,
    
While Marching to Mars through Odessa.

Samuel Roy Hagar (born October 13, 1947) is better known as Sammy Hagar.  After a brief career as a boxer in the footsteps of his father, Sammy became interested in music.  Hagar's first major success came from his work with the group Montrose.  After disagreements with Ronnie Montrose, Hagar departed from the group with bassist Bill Church and drummer Denny Carmassi.  He began a solo recording and touring career to increasing success, enjoying hits such as Red, Heavy Metal, Three Lock Box, and I Can't Drive 55.  Sammy would hook up with Journey guitarist Neal Schon on the HSAS project during this time, as well.

Van Halen was looking for a new vocalist after the departure of David Lee Roth.  Riding upon their previous contact with Hagar from a previous tour, they hired Hagar to fill the opening. With Hagar at the front, Van Halen produced four multi-platinum albums: 5150, OU812, For Unlawful Carnal Knowledge, and Balance.
