Cover art for Sky Blue lyrics by Peter Gabriel

I saw he Growing Tour, and he did say that.

This song reminds me of those times when you look up in the sky and it is that deep royal blue color that you just totally get lost in, while you are walking or just starring up...

I think the line "i keep moving to be stable" is a bit ironic as well, he cannot be stable where he is, so he moves on, yet the mere thought of 'moving' represents a transitory image, one that isn't stable.
