Kristin's father sent her the lyrics to "White Bikini Sand" in a letter. Kristin ignored the letter, and then two years later when the Throwing Muses were recording Limbo, she read the words and decided to record the song. She wanted to credit her father as the writer of the song, but he told her that he hadn't written it, she had - she sang it to him in a dream. Neither of them wanted to take credit for writing the song, which is why it ended up as a hidden track (via Hersh Head).
How to find it: Begins at 4:20 of track #12 ("Shark")
