The British composer, who wrote music for Kate Middleton and Prince William's wedding, has penned a lullaby for their firstborn child. Classical artist Hayley Westenra will record the song, sweetly titled "Sleep On."
"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," Mealor said in a statement.
"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," said Westenra.
Mealor's "Ubi Caritas" was one of the musical highlights when the Duke and Duchess of Cambridge tied the knot in 2011.
"Sleep On" is going to be included on Westenra's new album of lullabys—which, they say, will be shipped right over Will and Kate to help get their little prince or princess down for the night.
