Brumbies scrumhalf Ryan Lonergan will lead the Barbarians in their opening tour match against Northampton on September 3 (AEST time).
The Saints play in the green and gold strips but the colour scheme is more fitting for the Barbarians, who will run out a near identical team that played for Australia A against Portugal last week.
