The Hornsby Gang Show was born as humble first Hornsby Troop Concert in 1973 and was due to run only one night. The proceeds were to be used to send the troop to the 10th Australian Jamboree in Adelaide. The response was so good that another night had to be added and packed houses were recorded on both nights.

After the first show, everyone was talking about the hidden talent and it was agreed that this type of training activity should become a regular part of Scouting in Hornsby. The responsibility for the organisation and control was given to the Hornsby District. In 1974 we performed (again to packed houses) at Loreto Covent Hall at Normanhurst as "Showtime 74? with a larger cast which included Girl Guides. The early shows were financially backed by David Smith and guaranteed by members of Scouting in Hornsby" Jack Goyen, Arthur Ball & Bob MacDonald whose confidence in this training medium has been realised

In 1975 and 1976 as North Side Gang Show we performed at the Greenhalgh Theatre in the then College of Advanced Education at Lindfield. After a two year break, performances from 1979 to 1981 were held at the Pennant Hills Community Centre.

In 1983 we moved to Asquith Boys High School and in 1987 we became Hornsby Gang Show. A Hornsby Gang Show has been performed every year since with the exception of breaks in 1977,1978 and 1982 

​

In 2015 was a huge year, we moved into our new theatre at Barker College from Asquith Boys High School, sold more tickets than we have in living memory and performed to our biggest single audience (over 600 people at one show)

​

2020 will mark 49 years since our first show!

In 2021 the show moved to Castle Hill but hoping to come home in the near future.
