Coltrane shares a name with the legendary jazz saxophonist John Coltrane and apprentice jockey Callum Hutchinson certainly got a tune out of Andrew Balding's gelding to record a first Royal Ascot win.
It was a gruelling test on a warm day in Berkshire over two-and-a-half-miles with Coltrane battling a field of 19 runners in the Ascot Stakes, including the Willie Mullins' trained favourite Bring On The Night.
Coltrane has always had plenty of ability and warmed up for Ascot with a neck second in last month's Chester Cup.
In the race at Ascot, five pounds claimer Hutchinson provided a better ride than many of his professional jockey rivals, pushed to the lead in the final two furlongs and repelling Bring On The Night by three quarters of a length.
Arcadian Sunrise came home late to grab third for John Queally while 50/1 shot Going Gone took fourth, with last year's victor Reshoun in fifth,
Bouyant winning trainer Andrew Balding said: "I was happy at every point, Callum gave him a great ride. He was always where he needed to be and he found space, even when the other horse looked like he was going to come to him.
"I'm very proud of the jockey and of the horse. Five pounds can make a big difference at this trip and Rob (Hornby) was claimed by Ralph Beckett to ride his horse.
"It's a hot day and it might be a bit too much to ask to come back for the Queen Alexandra (on Saturday). He's won a Melrose so the Ebor is possible, there's are plenty of options."
Victorious jockey Hutchinson added: "I can't put it into words! A big thank you to the boss and to the Mariscottis (Coltrane's owners) for giving me such a great opportunity.
"The boss has been a great supporter this year and I've ridden six winners from 17 rides for him. He's been great to me, and I've been kicking on throughout the year. Hopefully this winner will give me a real kick and the season will keep on progressing.
"This horse is a big yard legend and I've ridden him a fair bit at home. People come in and out and he's the one they get to sit on - he's just a brilliant horse to have.
"My mum and my nan are here, so they'll be delighted to see that. Obviously my dad was a jump jockey and rode multiple Grade One winners, so that was something I wanted to do, although he never rode at Royal Ascot."
