From some dilatory reading in the early 1960s, I knew enough about viruses and their association with tumors in animals to understand that they might provide a relatively simple entry into a problem as complex as cancer.

Every cancer looks different. Every cancer has similarities to other cancers. And we're trying to milk those differences and similarities to do a better job of predicting how things are going to work out and making new drugs.

If you're in pop music, you've got to deal with the changing of the guard every few years. By the time the '70s arrived, I was well aware of the cyclical nature of the game. Pop music is a creature of the moment; it thrives on the mood of its time. Either you hook into that or you're not going to be part of it.

Every time I see documentaries or infomercials about little kids with cancer, I just freak out. It affects me on the highest emotional level... Anytime I think about it, it makes me sadder than anything I can think of.
