Saturday  marks the 30th anniversary of the drowning death of the Beach Boys‘ drummer and co-founder Dennis Wilson at age 39. For most of his life, Dennis was overshadowed by his older brother Brian, who wrote most of the group’s hits, and by his younger brother Carl, who sang lead on songs such as “God Only Knows” and “Good Vibrations.” As a youngster, Dennis was considered the least musical of the Wilson brothers, but it was his idea for Brian and cousin Mike Love to first write about surfing which resulted in their 1961 debut single “Surfin’.” It was the Wilson’s mother Audree who urged the group to include Dennis, who was then forced to play drums because, according to legend, he couldn’t play anything else.
