Although originally attributed to mere heart failure, the November death of Righteous Brothers singer Bobby Hatfield was actually caused by acute cocaine intoxication. According to Michigan's Kalamazoo Gazette newspaper, Kalamazoo's chief medical examiner received this information on Dec. 24, but kept it quiet until after the holidays, out of respect to Hatfield's family. "This is a shock to me," said Hatfield's Righteous partner Bill Medley. "I never saw him [use cocaine]. I knew absolutely nothing about it. If I had known, I would have said something to him."
