The Argentine musical icons are in a hospital of a sort, where the 2200 statues and monuments that dot Buenos Aires' parks and plazas are brought when they have suffered vandalism or decay.
City officials say about 20 pieces arrive each month - often dismembered, broken, sprayed with paint or stolen, either as collector's items or for scrap metal. Statues are sometimes damaged by angry protesters or toppled by people just for fun.
At the workshop, more than a dozen restorers repair stone and marble, clean away graffiti and mould missing appendages.
"We'd like to have less of this and focus only on preservation of outdoor works, restorations that would be due to age, and not to damage done intentionally," said Jorge Grimaz, who co-ordinates operations at the city's Monuments and Artworks shop.
The abundance of statuary and monuments, many acquired in France at the beginning of the 20th century, helps set the Argentine capital apart from other Latin American cities. Pollution and the humidity of the Argentine capital located on the banks of the Rio de la Plata affect the sculptures. But vandalism is by far their worst enemy.
The attacks on sculptures have increased as frustration simmers over Argentina's economic crisis.
A copy of Auguste Rodin's Le Penseur (The Thinker), located in the square in front of the Argentine Congress, has suffered the wrath of demonstrators who gather there to protest against politicians. The statue, cast in bronze from the original mould and signed by the French sculptor, was recently elevated on a pedestal to keep it away from the spray paint after a fence failed to safeguard it.
"We've had a lot of protests lately and the vandalism is on the rise," Grimaz said.
Even a statue of Argentine football star Lionel Messi has been vandalised - twice. Last year, the bronze statue was first cut in half at the waist and later chopped off just above the ankles. A tennis racket was torn from the hands of a sculpture of Argentine tennis great Gabriela Sabatini in 2014.
Other Argentine heroes and historical figures have suffered a similar fate.
Revolutionary leader Martin Guemes was robbed of his bronze sabre, so restorers at the workshop recently poured polyester resin into a rubber mould inside a plaster box to craft a replacement.
The workshop shelves hold dozens of heads, hands and other appendages awaiting attachment to damaged monuments. The head of Chile's Nobel Prize-winning poet Pablo Neruda sits covered on a stand near the head of former Argentine President Juan Peron.
A monument to South American independence leader Simon Bolivar has been sprayed so many times with graffiti that restorers have to clean it every 15 days.
The bronze pieces in a reproduction of The She-Wolf sculpture depicting the mythical founding of Rome, with Romulus and Remus, were stolen and have been replaced by polyester resin that has no resale value. The marble horns of two deer in a marble statue of the goddess Diana were broken off by straining dogs that had been leashed to them.
Only one figure seems to be sacred and off limits to everyone: Mother Teresa. A sculpture of the patron saint of the Archdiocese of Calcutta stands at Lezama park in Buenos Aires.
"They've never touched it," said Grimaz. "More than 10 years have passed and there's not another single work of art in that park that has not been at least stained with graffiti."
