Wilson was a member of The Four Kinsmen who always caught their audiences out with the unexpected.

But on the weekend the tables were turned on the musician who was carefully involved in coordinating the band's routines.

And it was Wilson, who was not only surprised, but discovered a talent he never knew he had.

When he was admitted to Wollongong hospital indefinitely for treatment in late April, after having a brain tumour removed at Prince of Wales Hospital, Shellharbour artist Natalija Vocanec asked him to help her produce a major artwork and would involve him every step of the way.

Ms Vocanec has visited him in hospital to talk about his life as part of the inspiration and to ask him to contribute to the musically-inspired piece, which will be auctioned by Leigh Stewart at the Graham Wilson fundraiser at the Lagoon Seafood Restaurant on July 21.

But on the weekend, the talented artist and art teacher thought she would give him some painting practice.

Wilson was taken to the Little Leonardo's Art Studio in Warilla to make what he thought was going to be his latest contribution to the artwork.

But Ms Vocanec surprised him by having Four Kinsmen YouTube clips playing and encouraged him to have some fun and quickly paint his own piece to the music.

It didn't take too much convincing as she talked him through it by asking him to imagine playing the music he was listening to while he made large sweeping brush strokes.

She then asked him to imagine music on a page and incorporate that into the finer elements of the piece which was completed in less than 10 minutes.

Along with running after-school and adult art classes, art-as-therapy is something Ms Vocanec has done many times with children and adults.

And she was impressed with Wilson's style as he took a flamboyant approach with a big smile on his face that did not leave.

He was almost dancing as he made the most of the opportunity to get away from his hospital bed.

Wilson surprised himself with the impromptu result and could not stop smiling over lunch afterwards.

"I can't believe that," he said.

"I was only mucking around."

Wilson said he had never painted before and Ms Vocanec was so impressed with what he produced she asked if she could keep his first work of art and hang it at her home.

She encouraged him to come back and do more.

Wilson is now eager to do a piece himself to be auctioned off with the artwork he is helping Ms Vocanec produce.

Whoever makes the top bid on July 21 will get to keep two masterpieces. They will be auctioned as a set.

One by a talented professional artist and the other by a talented musician.

During their art as therapy sessions Wilson is also going to teach Ms Vocanec the guitar.

Something he has missed doing with his student while he has been in hospital.

The art-as-therapy sessions come as the call goes out for more silent auction items for the fundraiser and the news that those who can’t attend the event can now make an online donation.
