Cover art for Sky Blue lyrics by Peter Gabriel

On the Growing Up concert tour DVD, Peter Gabriel mentions that some songs develop quickly, but that was not the case for this song. He gives the impression that he had been working on this song for a long time. He mentions that it wasn't until the addition of the choral voices at the end that it sent a chill down his spine and he realized he had it. Watching the performance on the DVD is equally chilling... it is haunting and conjurs up pictures of a chain gang sitting on death row dreaming of release.
