Presented by Petroc Trelawny. Concluding a concert from St David's Hall, Cardiff, the BBC National Orchestra of Wales, conducted by David Atherton live performs Holst's classic work The Planets. It depicts the awe and mystery of the night sky, ranging from the menace of Mars and the serene sweetness of Venus through to the joyous vigour of Jupiter - music that is said to have made the cleaners working at the hall during its first rehearsal put down their brushes and dance.
