On tour from the UK, the Worcestershire Youth Brass Band performed below ground to an intimate audience in the Yanchep National Park on July 25.
Conductor Nicky Dawson said she brought the band to Australia five years ago, but the children involved then had since grown up and moved on.
‘This is our return, our boomerang tour,’ she said.
‘They walked in (to the cave) and went wow ” we feel very privileged to have been allowed to come and play in this.’
The band included 32 musicians aged between 11 and 17 on a variety of brass instruments.
John Williams’ composition Olympic Fanfare provided a dramatic start to the performance, followed by a slower Michael Buble tune, Feeling Good, before a modern piece from the Avengers film soundtrack.
They also included two Robbie Williams songs, Candy and Let Me Entertain You, and Skyfall from the James Bond film.
Joining the audience of national parks staff and volunteers was a group of retirees from a Merriwa estate.
‘This was fabulous, I thoroughly enjoyed it,’ Kathleen Taylor said.
Joy Ballantyne said the performance was beautiful and she had not known the venue existed.
Both said they enjoyed the seven-minute Wall of Sound composed by Paul Lovatt-Cooper and A Stroll in the Park by Philip Sparke.
Wanneroo Mayor Tracey Roberts said the acoustics in the cave were sensational and the UK visitors got to see kangaroos lounging or leaping around Gloucester Lodge on their way to the cave.
