I was torn which song to post. Why Do I Feel? and My Pal Foot Foot (About a lost cat) are every bit as good as Philosophy of the World. They also did a Halloween tune that will show up here in a couple weeks.
Sounds like their daddy was worse than Mr. Jackson, Mr. Osmond and Mr. Cowsill put together.
The drummer died of old age (59) at an elderly care facility. It's very likely that she did not die of a disease because of the level of care necessary. Not hospice, not a medical care facility, an elderly care facility... My guess is that she had genetic or lifelong issues.
