I don't know Camille O' Sullivan, but Anna is one of the very few artists I'd approve to do more covers of Bowie, considering her natural talent of making cover versions sound like her own songs. I'd trust her to make his songs even more interesting, and that means something, because to me most of his songs are close to perfect. And Lady Grinning Soul is one of them, and yet Anna was capable to sort of recreate it with her incredibly distinctive voice.
