"I have no idea how they found this song," said Sam Rosenbaum. "I guess you can say it's divine intervention."
While not a professional musician — though he did once perform at his son's wedding — Rosenbaum always loved music.
Seven years after his father died, Rosenbaum said his father visited him in a dream. They didn't speak, but he felt as if they had communicated non-verbally.
He woke up, went down to his basement and composed Why Did You Leave Me Now?. About a year and a half ago, the song made it onto iTunes on Liz Rodrigues's album Just a Dream.
Seventeen years after he composed it, someone from HBO's True Blood contacted Rosenbaum about the song.
It will run during the closing credits of Sunday night's episode Life Matters.
