The late English entertainer was the host of a popular children's television program called Record Breakers, shown on the BBC from the 1970s to ’90s.

Co-hosted by the knowledgeable and jovial Guinness Book of World Records founder Norris McWhirter, the show featured people who led the planet, whether it be in the 100-metre sprint, hotdog eating or Serbian flight attendant Vesna Vulovic who survived the highest fall without a parachute when the plane she was in exploded at 10,160 metres above Czechoslovakia in 1972.

At the end of each episode, Castle, who himself set numerous world-records including the fastest tap dance of 1440 taps per minute (24 per second) which still stands, would sing the show's theme song.

A catchy number that anyone of school age through that era in the UK would be able to hum, its chorus line was "Dedication, dedication, dedication, that's what you need; If you want to be the best, if you want to beat the rest, whoa-oh, dedication's what you need."

It sounded better when Castle sang it, and the "whoa-oh" is pivotal.

Ariarne Titmus, Amy Cure and Jake Birtwhistle have followed the pullover-wearing presenter's words to soar almost as high as Ms Vulovic.

The time they have dedicated to their respective sports of swimming, cycling and both plus running (also known as triathlon) would be similar to that spent by McWhirter in memorising records.

Countless unsociable hours at their training venues combined with all three having to leave their beloved home state to pursue their sporting dreams demonstrates the sort of dedication Castle was warbling on about.

All had already achieved global success before this week's golden exploits on the Gold Coast.

The teenage Titmus burst onto the scene at last year's world championships, taking it up to the planet's undisputed queen of distance freestyle swimming, American Katie Ledecky.

At 25, Cure is a veritable veteran of track cycling, having won multiple junior and senior world titles.

Birtwhistle also claimed a world championship, in his sport's under-23 division, and has since been regularly beating the world's best, including the Katie Ledecky of triathlon, England's multiple European, world and Olympic champion Alistair Brownlee.

Naysayers are quick to point out that the Commonwealth Games are no Olympics - Ledecky, for one, has been a notable absentee.

But they do provide a well-lit stage for the likes of these three Tasmanians to show what they can do.

And given Australia and England's strength in the pool and velodrome and the same two nations plus South Africa and New Zealand's influence in triathlon, the Tassie trio knew they were guaranteed competition of Olympic proportions.

Ahead of Titmus's favourite events of 400 and 800m freestyles, the threesome had already landed as many golds as New Zealand and South Africa.

With a satisfying display of symmetry, all three were able to combine individual success with team glory.

Birtwhistle followed up his storming silver-medal winning finish to the triathlon by steering Australia to victory in the mixed team relay.

Titmus was also picked as the Australian anchor to deliver gold in the 4x200m relay having earlier won silver in the individual event (although using the term anchor in the water seems prone to disaster).

And Cure reversed the order, winning the scratch race three days after being a part of the team pursuit triumph to upgrade her silver and bronze medals from Glasgow to two golds on home soil.

What has also been fitting is how all three champions have been able to share their success with the parents whose support, encouragement and unquantifiable taxi services made it all possible.

Alan and Carmen Birtwhistle were hard to miss in their Jake-themed gold T-shirts at Southport Broadwater Parklands.

Steve and Robyn Titmus were even harder to miss at the neighbouring aquatic centre, particularly given the former's starring role in the new Channel Seven reality TV show Frantic Dad.

And Graeme and Delwyn Cure played contrasting roles at the Anna Meares Velodrome, dad abstaining from his commissaire duties for the couple of seconds it took to give Amy a congratulatory hug.

With the motto of these Games being “Share the dream”, here were six proud parents that have done, were doing and will continue to do exactly that.

And being rewarded for showing the same dedication as their athletic offspring.
