Mr Grattan said he had contacted many of the musicians through Facebook and was awaiting their replies before pressing on with the gigs.
Mr Wilson said doctors took his daughter off the first of several sedation drugs on Sunday afternoon as they began the process of waking her up for the first time since the car she was driving was T-boned.
"It is the one that will take the longest to wear off, so it will be a little while before the first effects are seen. We didn't spend much time with her this time, as they want her to have as little stimulation as possible while she is being brought out of the coma so she doesn't get too stressed ... which might happen if she can actually hear us at that point," he said.
"This is the point onwards that we start to find out the extent of her brain injury."
On Friday, Miss Wilson underwent a surgery to reattach the base of her skull to her spine.
On Thursday she had surgeries to insert a filter and repair the rear of her pelvis.
Miss Wilson was born with Crouzon's Syndrome, a condition that meant the bones of her skull were fused together, and had numerous surgeries to reshape her face and head.
The Bay of Plenty Times published stories and photos about her surgeries and bravery.
