Six months after the death of Joey Feek, her husband and fellow country music singer Rory Feek has revealed that he almost forgot his wife in happy days after watching her endure unimaginable pain due to cancer. The singer is releasing a documentary film titled To Joey, With Love that is in memory of his late wife.

"When Joey passed away in March and we came home to our farm, I couldn't remember my wife healthy. All those years of marriage and all that life that she had, until I started going through the footage and then I saw her come back to life. I was able, in making the film, to watch her life happen in real time again. It was amazing," Rory said during an interview with The Today Show's Savannah Guthrie.

In a separate interview with People, the singer who sang When I'm Gone along with his late wife, narrated his heartbreak after he learnt that Joey will not make it through. "When the time came that we realized that Joey was most likely not going to make it through this cancer... one of the hardest things was coming to realize that I was going to be back here again where I was before, but this time raising Indiana," an emotional Rory told the website.

Joey breathed her last in March after a prolonged battle with terminal cancer. She was 40. But the 51-year-old country singer revealed he had not prepared himself for the loss. "No, I wasn't as ready. None of us are," Rory said. "It's been, I don't know, how long? Five months? And I'm still not quite ready. That's the biggest thing I struggle with — I still walk around thinking, 'She's really not here? She's really not coming back?" he told CBS Sunday Morning.

The special film To Joey, With Love, is scheduled to be screened in theatres in the US on 20 September and 6 October.
