Comments by Neal Preston:

"Those nutty, crazy Zappas," people would say with a snicker – that's the way people looked upon them at the time. I was shooting Frank for PEOPLE and he had been reading the Financial Times that morning. And who would think of Frank Zappa reading the Financial Times? After that I shot him playing pingpong (the shoot was for PEOPLE magazine, after all), and the bird was flying around the table – and flew right onto his head. I saw that, and said to Frank, "Let's pose the bird on your head for a tighter shot." The look on the bird's face is classic (I seem to remember the bird was named "Bird Reynolds") as if it's saying, "Who the f*** is this guy underneath me?"
