Kate Garraway said it took "weeks of planning" to get her husband Derek to Elton John's concert on Monday.
The former lobbyist, 55, has been suffering from the effects of Covid for three years and requires constant care.
However, this week he went to see showstopper Elton perform at the 02 Arena with Kate, 55, and the couple's kids Darcey and Billy.
Opening up about the efforts required to get her husband there, Kate said on Smooth Radio: "Right up to the last minute, I wasn’t sure if it would be possible to get Derek there. It took weeks of planning and just days before, it looked like he would be too sick to attend. Even on the journey there, he seemed so weak.
"But as soon as we got into the stadium and Elton went on stage, he started weeping tears of joy, and squeezed my hand so tightly."
However, the Good Morning Britain host then admitted Derek had 'started shaking' and had to be taken outside the hall by his wife and nurses.
Thankfully, he appeared to rally, with Kate continuing: "After a while, I asked him if it was time to go and he said, ‘No… want to go back'".
It was already such a big achievement getting to the stadium, but nothing could have prepared the couple for what happened next.
In a heartfelt speech, Elton dedicated one of his songs to them.
Kate and Derek were hailed by the Can You Feel the Love star, who told the 20,000-strong crowd the couple had endured "really tough times".
"They’re inspiring" Elton said. "They’ve never given up and I’m so thrilled they’re here, I can’t believe they are here."
"I want to dedicate this song to the people I mentioned before, but especially to you guys."
Elton then went on to perform his 1974 hit Don't Let The Sun Go Down On Me in tribute to the Garraway family.
Speaking about the tribute, Kate said: "We were all in tears, the kids, Derek and even the nurses. It was completely unexpected. People around us were so lovely and started clapping which was an extraordinary moment we will all treasure forever and Elton made it possible."
On Good Morning Britain today, Richard Arnold explained Kate played her husband Sir Elton's tracks while he was recovering in hospital.
He said: "It's lovely to see them out and about because of course as we know it's quite the feat so it's wonderful that they got to share that moment together."
