A group of musicians wants to send the old Kosciuszko Bridge off with a bang — by performing Tchaikovsky’s “1812 Overture” as it is blown up later this year.

Trombonist Danny Flam, who has played with Jay Z and Kanye West, is petitioning the city and state to let his Kosciuszko Philharmonic Orchestra perform the overture — whose finale includes cannon fire — as the bridge linking Brooklyn and Queens is brought down.

“How awesome would it be if an orchestra could play the ‘1812 Overture,’ ‘London Bridge is Falling Down,’ music from ‘Titanic’ and other selections during the big event,” Flam writes in a pitch on the Web site iPetitions.com.

The overture, first performed in 1882, features prominently in Hollywood explosion scenes, including “Caddyshack.”

Tchaikovsky’s original composition calls for cannon fire 16 times in the 15-minute opus, and Flam hopes state wrecking crews can work in sync with the orchestra.

“It has explosions built into the piece,” Flam told The Post. ”They need to set off the detonator just as the music hits the best part.”

The proposal is every orchestra geek’s dream, according to another musician involved in the effort.

“What kid who plays the ‘1812 Overture’ doesn’t dream of playing it live for a bridge that gets blown up?” said Brooklyn trumpeter Ben Holmes, who has worked with indie bands Gogol Bordello and Vampire Weekend.

The state is in the midst of replacing the 78-year-old bridge, which carries the Brooklyn–Queens Expressway over Newtown Creek, with two new spans by 2020.

Gov. Cuomo announced in February that crews would demolish the bridge, which is controlled by the state, this summer by exploding its Brooklyn and Queens ramps before hauling away the middle section.

Blowing the bridge up instead of taking it apart will save the state months of work, Cuomo’s office said.

Flam is hoping to secure either a private space for the performance or to get a public-events permit for a spot nearby.

He said he plans to pay for loudspeakers and a stage by getting demolition companies to sponsor the event.

Officials have not set a date for the demolition and did not comment on Flam’s proposal, but did say they are working on some kind of send-off for the bridge.

“We’re still in the planning stage for the ceremonial and viewing aspects of the implosion, but we’re looking forward to sharing this moment with New Yorkers,” said Cuomo rep Jon Weinstein.
