They lined the path as the coffin, topped with flowers, was carried into the church while The Faith Hill song There You’ll Be was played.
Denise Nolan-Anderson’s eulogy said: “She really loved going to premieres and opening nights, having her beautiful hair and make-up done, and always was the life and soul of any big occasion.”
She said the singer had so many friends “who adored her”.
Describing her sister’s cancer diagnosis, she told the church: “She said the hair loss was the worst thing for her.”
She said the diagnosis, along with losing her husband Brian and sister Bernie, could have “destroyed” a lesser person.
Nolan-Anderson added: “Not Linda, instead she chose to help raise millions for cancer research.”
She said her sister showed “courage in the face of adversity”.
“It’s time to rest now Linda. The battle is over. You are free,” she said.
A recording of Linda singing When It’s Over was played after the eulogy.
