The collaborators David Bowie worked with to produce the Lazarus musical during his prolific final months hint at the possibility that more unreleased music may yet surface from the late singer's vaults.

The latest issue of MOJO takes readers behind the scenes of the show through interviews with a number of the show's creative principals, including producer Robert Fox, who said the team was aware of Bowie's failing health. "David told us that he wasn’t well," Fox explained. "He couldn’t be around for certain parts of the workshops and wanted us to know if he wasn’t around it was because he couldn’t, not because he’d lost interest. That’s when he said, 'We’ve got to do this. And crack on with it.'"

Bowie's efforts to blend into the production weren't terribly successful — as actor Michael C. Hall put it, "the molecules in the room would shift" when he tried sneaking into rehearsals — but they describe it as a triumph in every other respect, right down to Bowie's last-minute appearance at the show's opening night. Of particular interest to fans is the article's focus on the bonus tracks included in the Lazarus cast album, which saxophonist Donny McCaslin hints haven't been fully heard.

"There was at least one more song that I heard in its final version that is, mixed and mastered. It sounded great. I loved it," McCaslin revealed. "I don’t know what’s gonna happen with that, but I hope it comes out."
