It reached No. 6 in the US and No. 3 in the UK.

The Beach Boys are an American rock band formed in Hawthorne, California, in 1961. The group's original lineup consisted of brothers Brian, Dennis, and Carl Wilson, their cousin Mike Love, and friend Al Jardine. Distinguished by their vocal harmonies, adolescent-oriented lyrics, and musical ingenuity, they are one of the most influential acts of the rock era. They drew on the music of older pop vocal groups, 1950s rock and roll, and black R&B to create their unique sound. Under Brian's direction, they often incorporated classical or jazz elements and unconventional recording techniques in innovative ways.
