Sir Tom Jones thinks the BBC is a "cold machine".
The 'It's Not Unusual' hitmaker has blasted the media corporation after he was booted without warning from 'The Voice' in favour of Boy George.
In an extract from his autobiography 'Over the Top and Back', as published in The Sunday Times newspaper, he said: "What a cold place the BBC is. Sometimes you wonder whether it's run by humans or a machine in a basement.
"[Former boss Bill Cotton] knew intuitively what makes entertainment work for the British public. Sadly, there's not much of that at the BBC today."
Meanwhile, the 75-year-old singer blasted the executives' "sub-standard" behaviour and admitted he found the whole incident very "disappointing".
Writing in a Facebook post, he said at the time: "In good faith, as part of the team, I'd put the time in my schedule to be involved in Series 5, as I've done so for the last 4 years. I've supported the show and the BBC since the beginning. I was told yesterday, with no consultation or conversation of any kind, that I would not be returning. Having been through plenty of transformations throughout the years, I support and admire creative change.
"But being informed, as a matter of duty and respect, is an important part of creative relationships. This sub-standard behaviour from the executives is very disappointing. I will always admire the courage of the performers who participate in the show, as well as all the production staff who worked tirelessly to make a great family viewing experience for the audience at home. I wish the show well."
