Really!? That's rare. I went through two visually mint copies of this one until I gave up and got a mint Japanese issue on Sony that has no clicks or pops whatsoever. For some reason I had better luck with my UK issue of "four compositions" which only has a few isolated pops...
Most of mine have the occasional clicks and pops apart from the Frank Ricotti, which is near mint. That one was a good deal at £15 from Mole Jazz.
Having said that, I prefer to listen to all of these on the 1990s reissue CDs - sound is usually superior to the Realm LPs.
