One morning in 2010, a long-awaited piece of mail arrived at Deanna Martinez Neidlinger's home in Tacoma, Washington. It wasn't a Hogwarts letter, but for her three children – aged three, six and nine years old at the time – it might as well have been delivered by owl. Enclosed was a copy of the charity compilation album Jingle Spells 4, which included "Hogwarts Lullaby," a song that the family wrote and recorded together.
"The kids were able to hear themselves on a real-life CD and everything," Martinez Neidlinger remembers. "My three-year-old played the glockenspiel."
