I'm pretty sure I have the Saint Saens in my organ collection. I probably have 100 or so pipe organ LP's. The Crystal Clear Virgil Fox recordings also reach 16hz. My speakers do 18 but I'm good with that. Pipe organ sounds pretty dang real to me. I'll have to hunt for the one you mention. I am fairly certain that I have it.
I also have a group of Zubin Mehta but not sure if I have the one you spoke of. I always watched for him on LP's when I'd be hunting the bins at thrift shops. I used to find sealed 30 and 40 year old records for $2. I always checked the open ones and if they looked like they had been played or abused, put em back. It would take me awhile but was usually worth the effort.
