There was a Stokowski performance from 1958 with the Moscow
Radio Symphony" which I'm guessing is the same as the "USSR
Radio Symphony" released on Memories 2067/2068. They
actually have it at BRO.
According to the Stokowski Legacy site, which attempts to list every concert he ever conducted, he played the Prokofiev 5th just once 'live' on that tour, with the USSR State Radio Large Symphony Orchestra in the Great Hall of the Moscow Conservatory. He then recorded it in studio sessions for 'Melodya' and on MK 1551 it was simplified to USSR Radio Symphony Orchestra. As you rightly guess, it's the same recording as the Moscow Radio Symphony one.
Interesting to read in the 'Pristine' notes that Stokowski's US Premiere of the Prokofiev 6th Symphony was the first of only four that he ever gave of the work, in November & December 1949, and he returned to No. 5 just once more, in 1967 with the American Symphony.
