Paul Mealor the composer who wrote music for the royal wedding has written a lullaby for Kate Middleton and Prince William's baby.
The tune titled "Sleep On" was written because Paul thought it seemed a natural progression to accompany the next stage of their married life.
And according to Mirror.com: "Classical superstar Hayley Westenra has included the song on a new album of lullabies and a copy is to be sent to the couple to help them through any sleepless nights with their new arrival, due in July, and she has dedicated the album to the royal baby."
The 37 year old composer said: "After writing music for the Royal Wedding it seemed natural to provide the musical accompaniment for the next stage of the royal couple's journey together."
Hayley Westenra, who has performed for the Prince of Wales, said: "Paul and I got together to work on a song called Sleep On in honor of William and Kate's new arrival as it's such a joyous occasion which we can all celebrate."
