Just a point for your intertest
In the making of this film, the producers realised they had a massive music production on their hands. So much so, that the music basically overtook the film. So instead of just sending artists into a studio to do their bit, they decided to hold a huge country concert to celebrate the event.
It was staged in the now retired home of "THE GRAND OLE OPREY" To an audience wich far exceeded any expectations, such was the demand for tickets, they decided to take it one more step, and the concert, with all the stars performing, was recorded and released on a spin off, titled "Down From The Mountain"

Anyone who has seen the film on DVD would know this info, it is not exclusive to me, but as the original post stated it had been videoed, i am guessing this information may have been unknown.

Maybe worth trying to find a copy if you loved the music so much.
I certainly do!
