And, sources say, capo Anthony Rotondo is singing lots of hit tunes for the FBI and federal prosecutors in Manhattan, providing evidence against Garden State gangsters and a Genovese mobster charged with having a mole in the federal courthouse.

Rotondo, 44, has confirmed accounts by other DeCavalcante turncoats that Federico (Fritzi) Giovanelli alerted them in late 1999 that one of their associates was cooperating with the feds and that they were about to be indicted.

Rotondo, whose old man – DeCavalcante mobster Vincent Rotondo – was shot to death in 1988 and found with a bag of rotting fish in his spanking new Lincoln Continental, began talking to the feds before the Christmas holidays, sources said.

Rotondo's cooperation has already paid dividends. Last Friday, James Gallo, (left) 57, a longtime DeCavalcante soldier charged in several gangland style slayings with Rotondo, took a plea deal that calls for 25 years in prison.

According to court papers, Gallo and Rotondo were involved in several mob hits, including a 1989 John Gotti-triggered slaying of a private garbage hauler the Gambinos feared would cooperate when he was charged with racketeering.

Gallo admitted taking part in murder conspiracies going back to 1973, pleading guilty after becoming convinced that Rotondo, who had switched lawyers and was moved out of general population at the Metropolitan Correctional Center, was cooperating, sources said.

Of 21 mob defendants hit with a slew of racketeering charges two years ago, only Westley (The Kid) Paloscio (right) remains. Paloscio, charged with gambling and soliciting the Oct. 10, 1998 murder of degenerate gambler Joseph (Joey O) Masella, is scheduled for trial next month.

After Palermo cooperated, prosecutors, who initially charged Paloscio and Palermo with the murder, changed their theory about the slaying and dropped charges against Anthony Greco, the man initially accused of firing the fatal shots.

But they're holding fast on Paloscio, even after Judge Lawrence McKenna ruled last week that Masella's last words to a cop before he died – words that the feds say implicate Paloscio – cannot be used at trial.

"He's the lone defendant because he's a gambler charged with a crime he did not commit," said Paloscio's lawyer Joseph Tacopina, hinting he would concede his client's involvement in illegal gambling at trial.

Andrew Gigante, who guided his father 's wheel-chair in and out of court at his 1997 trial, was charged with racketeering yesterday for helping his old man run his crime family since going away to prison.

Vincent (Chin) Gigante, (right) son Andrew, 45, and six others, including the family's reputed acting boss, were charged with running lucrative extortion rackets on the docks in New York, New Jersey and Miami.

Through infiltration of the International Longshoremen's Association, in particular Local 1804-01 in New Jersey, the Genovese family reaped millions of dollars in illegal payments over the last decade, authorities charged.

All told, the racketeering indictment seeks to recoup $30 million from the Gigantes, family acting boss Ernest Muscarella, former acting boss Liborio (Barney) Bellomo (left) and four others.

Brooklyn U.S. Attorney Alan Vinegrad said that when Chin Gigante, now 73, began serving his 12-year prison term, he "gave up his crazy act" and used his son Andrew and others to carry out his directives.

"He gave up on the act and concentrated his energy on running the affairs

of the Genovese crime family from prison. He gave orders and he called the shots," said Vinegrad. (right)

Andrew is not a "made man" but in court papers prosecutors Paul Weinstein, Paul Schoeman and Daniel Dorsky said he "was a power in his own right"on the docks and should be detained as a danger to the community while he awaits trial.

They cited numerous conversations in which Genovese wiseguys told a turncoat associate about Andrew's dealings with them and described his status as a "confidant and conduit of messages to his father." (That's Andrew with his dad at left.)

"His close relationship to his father and his willingness to use that relationship to affect the operations of the Genovese family at its highest levels render him a serious danger to the community," the prosecutors said.

"I hope this is not an unfortunate situation of somebody's kid being punished for the sins of his father," Andrew's lawyer Peter Driscoll told reporters.

A detention hearing is scheduled for tomorrow.
