Lucy Haslam, and the DC Stories team behind the controversial medicinal cannabis documentary High as Mike, have challenged the songwriters to come up with a theme song for the Australian medicinal cannabis movement.

Every year the Songwriters Retreat sees several up-and-coming artists work intimately with established artists to work on songwriting, performance skills, creative flow and market presence.

This year's tutors include big names like Kevin Bennett, Shane Nicholson, Jeremy Edwards and Luke O'Shea, and Mrs Haslam has no doubt the talent pool can come up with a moving masterpiece.

"It is something that I have been thinking about for a long time," Mrs Haslam said.

"We need to create a people's movement in Australia, and we need music to unite that movement so this opportunity was perfect."

Dag owner and renowned artist John Krsulja runs the program, and saw this as the perfect opportunity to not only provide the backtrack to a national movement, but also as an out-of-the-box challenge for both artists and tutors.

Following the traditional public show on Saturday afternoon the crew will sit through a private screening of High as Mike alongside Mrs Haslam, the film crew and a few special guests, before heading into a private session to write and produce the song.

"It will be a great experience for everyone involved and hopefully we can get a great song and eventually a great outcome," Mrs Haslam said.

"We need it to go global, but also wanted it to remain Tamworth centric, like the documentary - people know where the movement started in Australia, and in the long term the region could see benefits from that.

"We have to keep moving forward, being creative, and be heard to keep pushing this agenda forward because people in Australia are still suffering unnecessarily."
