A former music teacher who worked on film and TV projects has been jailed for 12 years for dozens of sexual offences involving children over more than 40 years.
David Pickthall, who was appointed an MBE in 2015 for services to education and charity, worked as a teacher at Brentwood School in Essex and as a choirmaster in the London Borough of Havering when some of his offending happened.
The 66-year-old, of Ingrave Road, Brentwood, had admitted 29 counts of sexual offences against 19 people at an earlier Chelmsford Crown Court hearing.
In sentencing, Judge Mary Loram KC said: "For over two decades you took advantage of your position to abuse boys in your care."
