The melodrama spoofs continued as an occasional series over the next six years, with Oil Can Harry and Pearl Pureheart returning in thirteen more cartoons. Another memorable short was 1949's "The Perils of Pearl Pureheart", in which Oil Can Harry hypnotizes Pearl into singing "Carry Me Back to Old Virginny" on stage at an old saloon, where he vacuums up the tips thrown by the audience. Hypnotized for three and a half minutes of the six-minute cartoon, Pearl continues to sing as the battle between Harry and Mighty Mouse rages around her, even underwater.
