 The overture proved popular and went on to appear in numerous further concerts.Like many of Sullivan's early pieces, the overture is in the style of Mendelssohn and shows that "The Sapphire Necklace" was a more serious work than the comic operas for which Sullivan later became famous.The two other songs, "Over the Roof" and a now-lost recitative and prayer, "Then come not yet," were less successful.
