This is disc two of a three part set. On the only disc which I have actually seen of the set (Broadcast Twelve 5059), the orchestra is shown as simply Symphony Orchestra and the conductor is not identified. I have no reason to imagine that things are different on the other two discs. In the Broadcast list on Mike Thomas' mgthomas.co.uk website, the orchestra is identified as the Metropolitan Symphony Orchestra and the conductor as Stanley Chapple.
