Faryl Smith helped raise more than £2,700 for Cransley Hospice when she performed a concert in memory of her number one fan.
The teenage star from Kettering and singer Nigel Adair, of Burton Latimer, performed a concert in memory of Nessie Chapman at the Corn Market Hall, Kettering, on September 24, almost a year to the day after she died at the hospice of ovarian cancer.
Widower Robin Chapman, 74, who organised the night as a thank you to friends and family, said: “It was absolutely incredible.
“Nessie loved a party herself. It was what she would have loved.
“If she could have been there she would have been the life and soul of the party.”
At the end of the night Faryl, of Kettering, who shot to fame on Britain’s Got Talent in 2008, led the 160 guests in singing You’ll Never Walk Alone, one of Mrs Chapman’s favourite songs.
Mr Chapman, of Willow Road, said: “The atmosphere was incredible.”
Mrs Chapman’s grandson Martyn raised another £720 for the hospice by taking part in the Cransley Road Race on September 18.
