The couple told presenters Phillip Schofield and Holly Willoughby how Rupert's life changed forever in 1997 when he suffered severe brain injuries following a car accident.
The crash left him in a coma for two months and his family did not know if he was going to survive.
Before the accident Rupert was studying at the Guildford School of Music and was hoping to become a professional French horn player.
Brother-in-law Harry said it was Rupert's love of music that brought him back to his family.
"He had been in a coma for two months when his Dad brought in his French horn and they played his favourite pieces of music," he said.
"Rupert started to move his fingers, playing the notes and that was the first sign that he was still in there."
It's amazing the musical ability wasn't lost following the accident. It's just a miracle.
Escala performer Izzy Judd said her brother was an amazing character before the accident, describing him as a "wonderful musician and a popular boy".
She said: "It's amazing the musical ability wasn't lost following the accident and he can still play the French horn. It's just a miracle."
The couple got married last year in front of a huge crowd of their family and friends.
However it was Rupert who stole the show and had people in tears following a moving solo performance on his French horn.
"He was unbelieveable," said Harry.
"He is so much fun, he's such a character. I've only ever known Rupert post his accident and he's brought such happiness and positivity to my life."
However Harry admitted his brother-in-law does like to embarrass him in public.
"When we take him out he will always tell people, 'This is the drummer from McFly!' he said.
"It's really embarrassing and no matter how many times I tell him not to do it, he does it."
