The brothers are performing their popular Songs of Simon and Garfunkel concert as a special acoustic version, with just the two brothers on stage with their guitars and voices.

"We were both devastated and shocked by the bushfires this summer and wanted to come home to the Valley to perform a concert to not only raise some needed money, but to also be there for the community of the Valley," Pat ODonnell said.

headspace Bega provides a valuable service and hub to the youth of Bega and its surrounding towns by offering mental health and wellbeing, drug and alcohol counselling, physical and sexual health and education and vocational support.

"When we were growing up in the Valley in the '80s I'm sure Pat and I could definitely have benefited from having a place like headspace to go to," Andy O'Donnell said.

"We were lucky to have music in our lives.

"That's why we want to raise as much money as we can for them to perhaps give them an opportunity to provide extra staff, or whatever is needed to reach out to the youth."

The two-hour concert will feature the songs of Simon and Garfunkel in an intimate form stripped back.

The ODonnell brothers want to invite the community to come and share in the singing together with songs like Sounds of Silence, Homeward Bound, The Boxer and many others.

All of the ticket sales from this concert are going directly to headspace Bega and there are only 350 seats available.
