Back when the TV channels would sign off at midnight or later, they would always play the National Anthem, followed by a test pattern. While I remember it mostly being an instrumental version played by a marching band or an orchestra, a two-verse version with a woman singing it accompanied by an acoustic guitar was also popular.
As I came to find out, she was singing verse 4 in addition to the familiar first verse. In the ensuing years, I would occasionally find it in music books, but with only three of the four verses, verse 1, 2, and 4. It took San Francisco 49er quarterback Colin Kaepernick sitting during the pre-game playing of the National Anthem on August 26 for me to be reminded of verse 3.
