Hen Night gave trainer David Wachman and jockey Wayne Lordan back-to-back victories in the Platinum Stakes at Cork.
Successful with Latin Love 12 months ago, the duo struck with the Gigginstown Stud-owned filly.
Absent since finishing third to the subsequent Irish 1000 Guineas winner Bethrah at Leopardstown 12 weeks ago, the 10-1 shot came with a rattling run to storm past Famous a furlong out.
She stayed on strongly to win by two-and-a-half lengths from Maybe Grace, who grabbed the runner-up spot from long-time leader Famous close to home.
Disappointment of the race was the Mark Johnston-trained evens favourite St Moritz, who had every chance but weakened into fifth place.
Of Hen Night, Wachman said: "She had a break since the spring, but she is progressive and seems to go on any ground.
"I'll have to discuss it with the owners, but I wouldn't mind taking her to America and I have a couple of targets in mind out there.
"I'd be hoping to have a busy autumn with my team after having a quite enough time."
She's Our Mark (4-1) came from last to first to take the Group Three Give Thanks Stakes.
Pat Flynn's six-year-old mare swooped down the outside in the final furlong to beat Leo Gali by a length and a half with Zarebiya a short head away third. "I felt she had a good chance today and I feel now that she'll get a mile and six," said County Waterford-based Flynn.
"She only cost around 12 grand as a yearling and she has been an unreal servant as she's had well over 40 runs at this stage.
"We'll play it by ear with her now and we'll continue to aim her at these type of races. Between herself and Bahrain Storm -- they're keeping me in business."
Jockey Danny Grant was completing a double having struck earlier on Foolproof (11-2) for John Joseph Murphy in the Navigation Road Nursery.
Meanwhile, Banna Man proved the value of course and distance form at Galway as he took the feature Connacht Tribune Handicap Chase on the final day of the week-long festival.
Fourth earlier in the week over hurdles, Thomond O'Mara's 10-year-old was 6lb out of the handicap -- but knows his way around the Ballybrit venue after a win here two years ago, and was given a super ride by 7lb claimer Bryan Cooper.
It looked at one stage as if he would win with ease after the last, but in the end he had to be kept up to his work for a two-length success over Arkendale.
O'Mara said: "He won here on this day two years ago. He was thrown in here off a nice weight.
"He ran well here on Monday evening over hurdles and we decided to take our chance. I thought the ground might have been a shade quick.
"I'm delighted he won a big pot and Bryan was good on him. It's his first time riding for me."
Henry de Bromhead has another nice prospect for the bigger obstacles after Kilmurry (9-2) ran right away with the Galway Bay FM Beginners Chase.
Andrew Lynch barely had an anxious moment, leading three out and coming home 12 lengths clear of Wise Old Owl.
"He was always going to be a chaser so that's why we decided to kick on with him, even though he is only a five-year-old," said the winning trainer.
"There is a two-and-a-half-mile novice chase at Tipperary in October that springs to mind for him."
