On September 19th 1973, singer and musician, Gram Parsons, died of drug toxicity at the Joshua Tree Inn, California, aged only 26. Gram Parsons was one of the great, lost talents of rock music - combining country, folk and rock to create his own original sound. Often critically acclaimed, he pioneered his own blend of cosmic American music. But during his short life, he became almost as famous for his drug and drink consumption as he did for his music. Now, Forensic Pathologist Dr Michael Hunter is taking a fresh look at Gram Parsons autopsy and will reveal why such a seasoned drug user could have suddenly met his end on that night at the Joshua Tree Inn.
