Pannaway Restaurant in Rye will host a Jazz Jam Extravaganza in memory of the late Stanley “Tim” Jenkins Sr. on Sunday, Jan. 30. Jenkins, a long-time jazz fan, passed away recently after battling an extended illness. The concert will benefit his widow, local jazz singer Sharon Jones.

Guests who wish to participate in the jam can sign up when they arrive. They will perform on a first come, first served basis on one of two small stages in the restaurant. Drummers should use brushes and horn players should bring a mute; singers should bring charts for alternate keys.

The show takes place from 4 to 9 p.m. on Jan. 30 at Pannaway Restaurant, Rosewood Plaza, 150 Lafayette Road, Rye, 603-319-4200. There is no cover charge, but donations will go to Jones.
