Get your karaoke singing in now, Razzy's closes Saturday. ~Photo by Tom Nash By Tom Nash Fans of karaoke and free popcorn have only a few more nights to enjoy a popular Somerville Avenue bar. Razzy's, which in its five years has amassed a loyal following, will be shutting its doors for good on Saturday. Co-owner Nancy Maiullari said that the five-year lease on the building is up at the end of May, and the owner is seeking to sell the building for $900,000. "We tried to make a deal and it just didn't happen," Maiullari said. The bar will be open through May 29, and she stressed that no special events have been planned. Maiullari opened Razzy's in 2005 with her sister, Ruth Aylward. Friends cautioned against it after seeing the dive bar they were replacing, Jon's Place.

"When we first got the place, it was acceptable to do a line of coke off the toilet seat," Maiullari said. "Talk about an uphill battle."

The back room karaoke nights were introduced after she decided hosting gay or Latin nights would be too divisive.

"Whoever you are, whoever you love, we want you to be comfortable here," Maiullari said. "I think we accomplished that."

As the karaoke nights became more popular, aided by a growing population of reviewers for the Web site Yelp.com, attendees who showed up after 9 p.m. would often find they had to wait outside for others to leave. And it didn't matter who you knew.

"We're sticklers," Maiullari said. "One of my daughters left one night because she didn't want to wait in line."

Joe Aylward, a bartender at Razzy's since 2006, said the extra staff needed to help control the karaoke crowds was a marked change from his first days there, when the back room would often be empty on Saturday nights.

"It's a word of mouth thing," Aylward said of the bar's popularity. "There are people that come in here form Spring Hill and people from Medford and Stoneham. There's a guy in New York City who tries to come here once a week."

While Maiullari would only confirm that she will be retaining the bar's liquor license, Aylward said he is hopeful Razzy's will re-open in a new location.

"A job is a job," Aylward said, "but this place is part of my life."
