Forty years ago, a 50-man squad from the Los Angeles police and sheriff departments raided Neil Diamond’s home looking for drugs and turned up about an ounce of cannabis. The arrest was ironic because the Brooklyn-born singer released one of the all-time worst anti-cannabis songs eight years earlier. The heinous “Pot Smoker’s Song” from Velvet Gloves and Spit is a cheery prohibitionist anthem spiced up with real quotes from NYC rehab patients. Diamond himself must have been high to record such a horrible clunker that, per his own words, “almost cost me my career” because so many “people just laughed at it.” Adding to the irony of his 1976 arrest, the “Sweet Caroline” singer had to enter a drug aversion program to avoid arrest. He had, in fact, become a pot smoker himself.
