1. "The River"
Bruce Springsteen's younger sister Virginia was an 18-year-old high school senior in 1968 when her boyfriend accidentally got her pregnant. They got married and were forced to grow up very fast, and a little over a decade later, their plight was in Bruce's head when he wrote the title track to The River. He debuted it at the No Nukes concert in 1979 with his sister in the audience. She had no idea he had written a song about her. "Here I am totally exposed," she told writer Peter Ames Carlin. "I didn't like it at first – though now it's my favorite song." Amazingly, Virginia and her husband Mickey are still happily married nearly 50 years later.
