<P> The final vocal track was recorded between March and April 1966 at CBS Columbia Square, Hollywood, with the session engineered by Ralph Balantin and produced by Brian . The song features three voices on the track . Carl is featured on lead vocals, with Brian and Johnston backing him . Johnston explained that, "The really cute thing is that at the end of the session, Carl was really tired, and he went home . So Brian...remember, this was 8 - track, so, he now has these extra tracks at his disposal . But there were just the two of us . So in the fade, he's singing two of the three parts . He sang the top and the bottom part and I sang in the middle ." Brian used the production technique of double - tracking Carl's voice, so that his voice is simultaneously singing the same part twice, to give the vocal a fuller and richer sound; Brian used this technique often during the recording of Pet Sounds . The song's sessions concluded on April 11 . </P> <P> Per band archivist Craig Slowinski . </P> <Dl> <Dt> The Beach Boys </Dt> </Dl> <Dt> The Beach Boys </Dt>
