His Hall of Fame career began in 1968 with Katoomba-based radio station 2KA and, on Saturday night at Wentworth Park, Paul Ambrosoli will sign off for a final time.
Since age seven, Ambrosoli, 70, dreamed of being a broadcaster and, in an era of great race callers, "the voice of greyhound racing" retires at the top of his game.
His first race call on live radio was from the Wollongong track - the site of WIN Stadium - and the state government-run NSW TAB was just making its way.
Ambrosoli - PA to his legion of fans - has seen the best of the best in all three racing codes.
From Tulloch and Emancipation to Kingston Town, Hondo Grattan and Paleface Adios, Zoom Top, Roman Earl, National Lass and Miata. Champions all.
He has seen the landscape of gambling - and racing - change entirely.
His accuracy and capacity to call on the run is quite remarkable.
A keen punter, Ambrosoli has, infrequently, been in the betting ring when the starter asked handlers to place the dogs in the starting boxes.
This writer had first-hand experience of one incident at Dapto a decade back.
PA was in an earnest conversation about greyhound breeding when chimes rang out to indicate the dogs were being placed in the boxes.
Departing like a startled gazelle, PA raced upstairs to his broadcast position, arrived in the nick of time for the jump and called the race flawlessly.
There was no time to get comfortable or rehearse names. Remarkable.
The advent of Club Superstation in 1996 - the precursor to Sky Channel - changed the face of wagering and racetrack attendance.
Before fans could watch the action live from the comfort of their homes, Ambrosoli painted a picture for greyhound racing's stay-at-home punters.
He was and is the best.
Retirement has come a little quicker than he and his devoted wife Pat might have considered but it has been well earned.
His granddaughter Claire Nutman is making her way as a jockey and he can ease back and watch Claire progress in the tough gallops world.
Tim Newbold will take Paul's place at the microphone as Sky Racing's No 1 greyhound caller in NSW.
The Novocastrian is a genuine talent, but there will never be another Paul Ambrosoli.
