Can't believe I've never noticed this thing on Doolittle before. I've lost count of how many times I've played the album, and often as I do I will read the lyrics and study the artwork. I've studied the photos so much but only just now did I see the little UFO etching in the bottom left picture on the back page of the booklet. Must've been the turning point for their more space/alien orientated music.
Amazing topic I know, but it's been ages since my last post
