Larsman is likely correct; I haven't purchased any of the new 45 RPM re-issues but the early Genesis stuff has inconsistent mastering.
Regardless, my best 33.3 RPM copy of Nursery Crime was pressed by Nippon Phonograph, item RJ-7302 copyright 1978. It has the quietest vinyl out of the three I have.
It may be difficult to find. Good luck!
