Another Australian here.
I play in a Bush band...the Bell Bird Bush Band for square dances
(aka bush dances) . The band consists of Keyboard ( Wilma) Violin ( Bob) and guitar, vocals and harmonica ( Allen ).
Now that I am retired I also play in a trio for Nursing and retirement homes ( all World War 1 and 2 songs and 1930s and 1940s music ). Quite delightful. Some of the old music had beautiful chord progressions and it should be nurtured and played forever.
