THEY range in age from 13 to 91; some trained at the Sydney Conservatorium of Music and others became musicians later in life.
But they will unite this Sunday, March 8, for the moving A Salute to Our Diggers concert.
They are known as Sutherland Shire Brass — formed in the early 1950s and now with 20 members.
President Jane Hall said that of all the performances they do, their Anzac Day appearances are those which they most enjoy.
Their Sutherland Shire Entertainment Centre concert this Sunday will be special, as it commemorates the 100th anniversary of the April 25 Anzac landings at Gallipoli in World War I.
"Take a walk down memory lane as you listen to tunes and marches of the [world] wars," she said.
"There are tunes to rally the troops, songs to bring people together and marches to move you."
Some of the tunes will include Nightfall in Camp, Keep Smiling Through (medley), Bless 'Em All and tunes made famous by The Andrews Sisters.
"There is satisfaction in playing with a group and making really good sounds, watching the audience and listening," Ms Hall said.
"This is the first Anzac concert targeting the music through the wars."
A highlight will be the reading of actual letters from soldiers.
Other performances in the band's musical year will include playing at Cronulla Sharks NRL games and Anzac Day ceremonies at Sutherland and Kingsgrove. Sometimes band members go to the city after these ceremonies to take part in larger ceremonies.
A Salute to Our Diggers, Sutherland Entertainment Centre, Eton Street, Sutherland at 2pm this Sunday, March 8.
