I recall an Acquitted by Mirrors piece from around the Naughty Boys sessions (early 1983?) where Bill mentioned the experience of recording with YMO. I believe there was a remark along the lines of "I wish they'd taken a few more chances with the [final] mix" (referring specifically to Naughty Boys, presumably the vocal version). I'll try to track down that issue of the 'zine; it's buried in a box somewhere. Meanwhile, here's the full instrumental version of Naughty Boys. https://youtu.be/q0yhb_0nXk4
