 That is a suite from a little-known opera by Sergei Prokofiev called The Duenna. The suite actually has nothing to do with the opera in title or subject matter, as it's called Summer Night. The opera is based on a play by Richard Brinsley Sheridan, and it's also called Betrothal in a Monastery. That was the Tom Perra Philharmonic Orchestra, and Leonid Green was the conductor.
