This is about Megan's father. He left when she was a small child, and returned when she was a older child. However, this turned out badly, and the police were called on one night when he became physically abusive towards her mother. Running out of the house, Megan screamed at one of the officers, "I'll pay you to shoot him!"
"Islands in the Stream" was originally written by The Bee Gees as an R&B song. It was originally written by the brothers for Marvin Gaye, however it was recorded instead as a duet by Kenny Rogers and Dolly Parton with the Gibb Brothers also contributing vocals.
