Al if I’m unable to find this CD is there an alternative good organ recording you might suggest?
Yup:
https://www.amazon.com/Saint-Sa%C3%ABns-Symphony-No-3-Camille/dp/B000003CSK/ref=sr_1_1?s=music&ie=UTF8&qid=1469925056&sr=1-1&keywords=cd-80051 Saint-Saëns’ Symphony No. 3, known as the "Organ Symphony," is music that I would expect to have much broader appeal than the pieces on the M&K disc. And I would certainly consider your use of the word "majestic" to be applicable to it as well.
I have this on the original 1980 Telarc LP. Don’t let the fact that it was digitally recorded and mastered in the early days of digital discourage you; the sonics of many of the digital recordings that were originally issued on LP by Telarc prior to and around the time CDs came into being are excellent.
That said, assuming that the CD was created with no added dynamic compression relative to whatever minimal amount (if any) may be present on the LP, I disavow any responsibility for what may happen if and probably when some of the passages on this recording drive your amp well into clipping :-)
