The July 1964 release of the Beach Boys' sixth album "All Summer Long" marked an end to the group's beach-themed period. From then, their recorded material took a significantly different stylistic and lyrical path. In January 1965, to focus his efforts on writing and recording, 22-year-old Brian Wilson declared to his bandmates that he would not accompany them on future concert tours. The rest of the group – Brian's brothers Carl and Dennis, their cousin Mike Love, and their friend Al Jardine – continued to tour without Wilson, who was replaced on the road by Bruce Johnston of Bruce & Terry.
