Finding Nemo: The Musical rare pre-show music?

[Toothy7564]

Listen closely to the beginning of this and you can hear instrumental, softer versions of some of the main songs such as "Where's My Dad" (first two minutes), "Go with the Flow" (roughly around the 2:00 mark), and "We Swim Together" (4:25). Two other songs I know that are in this style are "Big Blue World" and "Just Keep Swimming". They sound so good during this pre-show section. Just one problem: There is no clean rip of them ANYWHERE as far as I know. The only way they exist on YouTube is recorded through cameras and often, have audience noises or loud people talking over them, which is a shame. They don't even seem available for purchase. I'm sure those of you who visited this attraction during 2010-2020 will recognize at least some of these specific pre-show versions.

Which brings me to the questions... are they indeed available anywhere? I know this might not be an easy question especially because I think the updated version of Finding Nemo: The Musical tossed them altogether, but it's apparently been twelve years since someone last asked here, and I figured maybe things have changed since then. Thank you in advance.
