Vanessa Amorosi will sing a tribute song at the funeral service of sports commentator Clinton Grybas today.
Melbourne-born Amorosi will sing Shine, which topped the Australian charts and highlighted her as a star when she performed at the opening and closing ceremonies of the Sydney Olympics.

It is believed Grybas, 32, was fond of the song and of Amorosi as a performer, and that Foxtel arranged for her to sing at the service.

Mike Brady will sing another Grybas favourite, the timeless Up There Cazaly.

Delivering eulogies will be his girlfriend, Laurenna Toulmin, brother Ashley, and 3AW colleagues and close friends Gerard Healy and Graeme Bond.

A video produced by Foxtel of Grybas's personal and professional life will be shown.

Foxtel interviewed many of his friends and colleagues for the video.

The service, with broadcasting veteran Tony Charlton as MC, is expected to attract more than 1000 mourners.

It will be held at the CityLife Church in Wantirna South.

Grybas was found dead next to his bed in his 15th-storey Southbank apartment 10 days ago.

An autopsy has been performed but the cause of death is not yet known.

Police said his death was not suspicious.

There has been speculation he fell while sleepwalking.
