Springfield, who died in 1999, lived at 38-40 Aubrey Walk in Kensington from 1968 to 1972, while she was at the height of her fame.
A plaque was installed outside the property by the Heritage Foundation in 2001 but “disappeared” during renovation works earlier this year.
Unveiling a replacement plaque, Gibb, president of the Heritage Foundation, said: “She could do no wrong. It’s got nothing to do with the sound or production, it was her – and that is the measure of greatness. She will be great forever.”
He said the plaque was “incredibly important” to honour her. “She is probably the greatest female popular singer in the modern pop rock era – since 1963, there’s been no one to match her. .
Gibb said he met the singer several times. He said: “We weren’t close friends but we were acquainted.
“She was shy, insecure, all the hallmarks of an artist that is great in spite of their own feelings.”
