Now they’ll be singin’ the blues.

A karaoke bar in Queens was shut down after investigators found the club was serving indoor food and alcohol to about 75 people on Sunday night, authorities said.

The club, SOHO KTV & Bar, on Farrington Street near 32nd Avenue in Flushing was raided by deputies from the city’s Sheriff’s Office soon after midnight on Monday morning, authorities said.

All of the club-goers were shuffled out of the bar and two managers were given desk appearance tickets for running the speakeasy karaoke joint, the Sheriff’s Office said.

Li Zeng Meng, 30, and Chen Yong Quan, 44, were hit with tickets for violating the mayor’s emergency order that could lead to their liquor license being pulled.

Meng and Quan could not be reached for comment.
