I did grow up in the United States and so I learned at a young age the Star Spangled banner. I think it was when I was in kindergarten. That was at least probably the first time I had heard it and recognized it. On top of this of course I heard it in sporting events as a kid. When I was growing up football often played on the TV because my dad used to play division one for CU. With the song being played around me constantly I must’ve picked it up pretty quick. It was also a common occurrence for my parents to sing to me as a kid so music was already a significant part of my family.
