This is the lead single from Leona Lewis' Christmas collection album Christmas, With Love
. The song is about special occasions from a child's point of view. The singer told Perez Hilton
that she wanted to express the happiness that comes from anticipation of a big event. "'One More Sleep is basically, it's a thing that a lot of kids say like, there's three days left until we're doing something fun," Lewis explained. "Like it's your birthday or Christmas, you'll be like "oh its three more sleeps left, count down to one more sleep left!" And 'One More Sleep' is really about that feeling."
"For me I'm on promo and touring and I'm away for so much of the year, but Christmas day is the one day I look forward to the most because I know I'm getting a day off," Lewis continued. "I know I'm going to see my friends and my family. I know I'm going to see my boy, like it's so exciting for me. So literally that song is that feeling, it encompasses that whole song. It's just the excitement, almost a childlike excitement that you have the night before Christmas. It's really very close to my heart, so it was really fun."
