Cath says that competition was fierce amongst local groups to win the competition - some even produced 'fliers' telling their fans to turn up and vote for them on the night.
She says her dad was determined that everything would be fair and above board:
"He decided in the first instance that it would be audience voting, they would all have a voting slip and vote on the night.
The Cossacks won twice, in April and December 1964.
"But when it came to the Grand Final, there was so much campaigning going on with the bands that were in the final, to get their hordes of fans in to vote for them, he decided that perhaps it would be better to have a totally independent panel of judges.
"He asked five people to be judges on the night, and they arrived at The Winter Gardens, nobody knew who they were, and he asked them to judge on appearance, musical ability, vocal ability - about seven different categories - so it was all done perfectly fairly."
She still has the original judges voting slips, filled out on the night of the contest.
One of the reasons that competition was so fierce was that the winning group stood a good chance of appearing on television, thanks to a deal struck by Cath's dad:
"He'd actually arranged with the TV company that they could make an appearance BEFORE the final had actually taken place - they'd take them without audition.
"It was called For Teenagers Only - it was a 20 minute programme on a Thursday night, but they'd normally got two or three bands on.
The Cherokees stage outfits and live act got them a TV appearance.
"The first band we took there were The Playboys, who won the first contest, and when we went to record that, Dad took photos of The Cherokees with him.
"They used to dress in full Red Indian regalia, and looked very colourful on stage, and on the strength of that we got an audition for The Cherokkes, and a girl singer called Jackie Pantin.
"ATV said they would use them, and gave us four days notice of The Cherokees and Jackie Pantin appearing together on the programme."
