Orana music teacher Sarah Draper said some of the students told her it was the most exciting day of their life.
‘I had to pick the 10 best students, and I told them it was like winning a golden ticket from Charlie and the Chocolate Factory,’ she said.
‘The original plan was to use a 100-voice children’s choir but they could not find a large enough place to record. We recorded the melody and two harmonies numerous times so it could be layered to make it sound like 100 voices.’
Mrs Draper said Egan was looking for a children’s choir and she got the students involved in the recording through her role as secretary and principle horn player in the WA Brass Band.
Egan flew from Alice Springs to record with musical director Erik Kowarski in his private recording studio Pocket Universe.
‘At the end of the session Erik and Ted were quite impressed with the standard of their singing,’ Mrs Draper said.
Egan hoped to publish a book for the centenary and had received interest from filmmakers to produce a documentary.
The track has received international attention from the embassy in France.
The song was a re-released version of Mr Egan’s previous track The Anzacs and will be available next year for the centenary.
