Johnny D’s Uptown Restaurant and Music Club is going out with a bang — and the clash of cymbals and honking of trumpets.

The whole community is welcome to join the fun.

The restaurant in Somerville’s Davis Square in July said it would be closing its doors after almost 50 years in business. It recently announced plans for its final farewell, a musical extravaganza that will feature a jazz-infused brass instrument procession through the square.

“Yes, people, it’s almost closing time and you are all invited to celebrate with us,’’ restaurant officials wrote on Facebook, referring to an announcement on local music website Vanyaland.

It was first thought that the club, which has hosted live music by national and local acts for decades, would close in January or February. The new plans call for it to close in March.

Johnny D’s opened in 1969, first as a bar, then as a country music club. It later became a music venue and restaurant.

Plans call for the conversion of it into a mixed-use building, with commercial space at street level. A three-story residential building will rise above it.

The “Final Day’’ celebration will feature Boston-based Revolutionary Snake Ensemble; and Second Line Social Aid and Pleasure Society Brass Band, a 30-piece, New Orleans-style street act, the eatery’s website said. The procession through Davis Square will begin at 5:30 p.m. on Sunday, March 13, according to organizers.

“We look forward to celebrating and bidding a proper farewell with you all,’’ the restaurant said on its website.
