Nobody tops Ealing Swimming Club when it comes to boy bands.
Everyone tried again at the recent London Regional Championships, but like all the rest this season, quartets from the Gurnell Leisure Centre outfit proved pretty hard to beat.
The 'A' team of Ben Levart, Alexander Farrell, Cristian Rotundu and Cain Franchi-Webster took were on song to take gold in the 4x100m freestyle, and silver went to the 'B' quartet: Joseph Sheehan, Joao Matias, Tudor Puszet and Aaron Pullen.
The 14-16 year-olds: Jahrel Marphy, Bryce Puszet, Joe Kelly and Reef Hook also crowded top step on the podium and then took silver in the longer 4x200m.
In fact, ESC needed a spare tin of Brasso to shine their medals as they hauled away 10 gold, 11 silver and four bronze from the 2012 Olympic pool at the London Aquatic Centre.
The silver lining the pockets of Maisie Jameson, Rebecca Dutfield, Charlotte Humphries and Sofia Tedeschi-Atkins was the result of their efforts in the 4x100m relay. Jameson then took a breath before notching 26.71s in the senior 50m free for silver.
Ealing took a clean sweep of medals in the 16 year old boys 50m back. Murphy beat team-mate Hook by one hundredth of a second, with Puszet in third. Earlier in the day, Jahrel won 50m fly.
Lucy Thornton grabbed silver in the 50m fly and Paige Powell, bronze in 50m freestyle.
Brodie Judge impressed once more with a string of personal best performances 50 fly (29.30), backstroke (30.87) and 50m free (27.55), with two golds and a silver currently placing her top five of national qualifying rankings for each.
Anton Akopian dead heated for first in 50m freestyle, his 25.93 seconds currently the joint third-fastest in the country for his age group.
In the younger age groups, Auryn White raced to silver in 50m freestyle and Harrison Filby put in another personal best swim to claim bronze in 50m breast.
Also in the 50m breast, Pietro Lombardo (12) swam well to take silver. Ealing's senior swimmers also cut a swathe through the water.
Cristian Rotundu took two titles (50 fly & back), Cain Franchi-Webster won the 50m free ahead of Alexander Farrell who took silver and added a bronze in 50m breast. Joao Matias was second in 50 fly.
Meanwhile, ESC head coach Dave Heathcock has been selected as Head Coach for the Great Britain swimming team travelling to the inaugural European Games in Baku, Azerbaijan.
This is just the latest recognition in Heathcock's illustrious coaching career, having placed a swimmer in a final at every senior national long or short course championships since 1976.
He said: “It’s a great honour for me to be head coach. We have selected a very strong and talented group of swimmers and this will be a great step in their international level development.”
One familiar face for Heathcock in Baku will be ESC swimmer Ana-Maria Damjanovska representing her native Macedonia at 50 and 100m free.
