“We knew we wanted to use the original vocal tracks, that was no question,” says the Pohlad. “But we also were hoping — and it turned out to be true — that Paul could actually sing. We were able to use his voice for those times when Brian is rehearsing and then, in certain cases, the recording sessions will start with Paul’s voice and we blended it with Brian’s voice and the rest of the Beach Boys as the song plays out. He is very committed. It was a lot of milkshakes and all that kind of thing in getting ready for the role. Of course, you can’t always predict exactly where the weight’s going to go on an individual person, so we were doing a little bit of scrambling in the immediate days before shooting with sit-ups and all that, just trying to mold it in the right way. But he really did a lot to prepare.”
