I always found David Bowie to be a tad creepy -- thanks a lot, Labyrinth -- but I've always loved Space Oddity as one of his greatest songs. That and Fame... It's already something of a spaced-out nursery rhyme, so a children's book is a perfect medium shift.
Andrew Kolb created this Bowie-inspired picture book that follows Major Tom on his voyage to the stars. I might just pick it up. Here's a look. That said, I'm not sure "Ashes to Ashes" would translate quite as well. [Kolb Is Neat]
