Willow Smith's ethereal vocals were chosen for a track, "Bird Song," recently released by Sean Ono Lennon. The track was written "years ago" with the late Carrie Fisher. Lennon decided to record "Bird Song" following Fisher's death as a stunning tribute to his longtime friend.
Lennon penned a statement about the track in its SoundCloud description:
Carrie and I wrote this song years ago. When she died I just felt I had to record it. This is only a demo unmixed, we only had a few hours to record it. But the lyrics she wrote with me I think are marvelous. Carrie and I used to stay up til dawn chatting and pontificating about life. They were my best moments. Anyway...we wrote a song about staying up too late and hearing the birds sing. Willow Smith is a prodigal angel and was generous enough to lend her golden voice to this little tune.
