New pictures emerge of the Rolling Stones, Pink Floyd, The Who, and Paul McCartney —
"I shot Paul McCartney in the Mojave desert in California in 1976," says Po. "It was amazing to be there at that time, when he had just left the Beatles and was embarking on his solo career with a new band. In the middle of the day, he sent off a limo to get supplies, and we ended up having a barbecue in the middle of the desert. It was incredible. He was telling us all about what it was like for him being in the Beatles, and how free he felt afterward. Those intimate conversations were more valuable than anything, because they influenced the pictures and made them fresher and more informal."
