One of Linda’s friends, the wife of Sir Tom’s first manager Gordon Mills, believed there was a reason Linda struggled with her husband’s dalliances, and the reason stemmed from when the singer was first brought onto the entertainment scene.
Mills introduced Sir Tom to the world in 1965, naming him a 22-year-old single coal miner from Wales.
The truth, however, was very different, as Sir Tom was in fact 24-years-old, married with a seven-year-old son, Mark, and had never been down a mine in his life.
However, the truth had to come out, and Linda did one of her only ever interviews.

She said: “I feel alive when he comes though the door, whatever the time of day or night is.”
According to Mills’ wife Jo, Linda’s insecurities could have come from that early description of the “single” Sir Tom, which reportedly made her feel she was “not good enough” for her husband.
Mills said: “I think from the very beginning, Linda was made to feel as if she mustn’t exist in his life.
“It is sad because she is a lovely person, very warm, and if only she had got that confidence initially, she would have been very different, I am sure.”

He added: “She always stayed very much in the background.”
Other confidantes of Linda have reported she even said: “I never felt good enough to be Tom’s wife,” which was a truly sad admission.
For Sir Tom, however, it was a very different story, as he explained in his autobiography how he never loved anyone like her.
In the 2015 autobiography Over the Top and Back, Sir Tom revealed he first fell for Linda when they were both 12-years-old.
He was diagnosed with tuberculosis and spent two years in bed convalescing, but by the time he had recovered and they were 15-years-old, he had asked her out for a date.

Sir Tom recounted how Linda would smile at him as they walked to school in South Glamorgan, and the pair married shortly after her 16th birthday as she had fallen pregnant with their son Mark.
Linda then gave birth to Mark just a month after their wedding.
Sir Tom wrote in his autobiography he had “never had that feeling for anyone else, I don’t think you can fall in love more than once”.
The singer also strongly disagreed with the notion he was ‘better’, saying she was “a cut above me academically and a cut above me socially, too.”
For Sir Tom, the best times between them before her death was when they were speaking on the phone.

In an interview in 2015, Sir Tom said: “When you’re face to face with somebody, you realise that time has gone on, but when you’re on the phone we’re both young again.
“We haven’t aged on the phone. You’re not looking at one another, I’m looking at an old picture I carry around with me and leave by the bed.
“She says: ‘I don’t look like that any more.’
“I say: ‘I know you don’t, but it brings back wonderful memories.’”
Sir Tom can be seen on The Voice on Saturday at 8.30pm, for the final of the ITV show
