Prince William has said he would like the Princess Diana memorial concert to be a chance to remember all the "amazing things" his mother did.
The princes paid tribute to their mother in the interview
In a BBC interview with presenter Fearne Cotton, Prince William and Prince Harry talked of their excitement ahead of the 1 July concert.
They also talked movingly about their mother, explaining that not a day passed without them thinking of her.
The concert will mark the 10th anniversary of Princess Diana's death.
Taking place at Wembley Stadium and organised by the princes, it will feature past and present stars including Sir Tom Jones, rapper P Diddy, Sir Elton John and band Supertramp - one of Diana's favourites.
Prince William said he and his brother had wanted more than a memorial service to celebrate their mother's life.
"We wanted something that would really bring her whole spirit - her joy of life and everything that we thought she stood for - a bit more to the point and a concert of this magnitude balanced with the service will be a wonderful way to remember her," he said.
He added that he felt a concert featuring some of Diana's favourite artists would be a fitting way to remember her 10 years after her death in a Paris car accident.

"We used to catch her dancing to her music - we'd walk out the room rather embarrassed that our mother was just dancing around," Prince William said.
"It was a big release for her and she had many artists that she loved listening to."
The prince said a key reason for the concert was to encourage people to remember their mother in a positive light and counter criticism of her.
"We want this year to go by and for people to remember all those good things she did," he said.
"After ten years there's been a rumbling of people bringing up the bad and over time people seem to forget - or have forgotten - all the amazing things she did and what an amazing person she was."
During the interview, which will be screened on BBC One in full on 29 June, the princes paid tribute to their mother.
"She did everything because she felt it was right and it was what she wanted to do," Prince William said.
"She didn't go by what she thought the best thing was to do or be told to do something, she would do it from the heart and fully immerse herself into it and she cared, she cared massively.
"We were left in no doubt that we were the most important thing in her life and then after that there was everyone else, there were all her charities and everything like that and to me that's a really good philosophy - she just loved caring for people and she loved helping."
The princes also said they had desperately missed their mother but had learned to deal with their sense of loss.
Prince William said: "We were so lucky to have her as our mother and there's not a day that goes past when we don't think about her and miss her influence because she was a massive example to both of us.
"It's one of those things that is very sad but you learn to deal with it and there are plenty of other people out there who have got the same or worse problems than we've had."
Prince Harry added: "She was a happy, fun, bubbly person who cared for so many people. She's very much missed by not only us, but by a lot of people and I think that's all that needs to be said, really."
Princess Diana died, aged 36, along with her companion Dodi Al Fayed, 42, when the Mercedes they were in crashed in the Pont de l'Alma tunnel in 1997.
Last week Channel 4 broadcast photos of the crash, despite objections from her sons.
Full inquests into the deaths of Princess Diana and Mr Al Fayed are expected to take place in October.
A three-year inquiry conducted by former Metropolitan Police chief Lord Stevens concluded that the princess had died in a tragic accident.
