Chris' page says:
This was to be the 1st single from "NYC Ghosts & Flowers" but it was never released. Nevermind was probably an edit, and Lightnin' was live from the All Tomorrow's Parties festival on April 8th, 2000.
Apparently a German 7" (pictured) containing "Nevermind" and "Renegade Princess" (LP versions) exists!
That would have been a tasty 7'!
