Those of us who have mastered eating a sandwich with one hand while typing with the other know that sneaking away from work during the lunch hour can sometimes prove difficult. Happenings at the Harman, the line-up of Shakespeare Theatre Company’s free noon performances on Wednesdays, always sound so promising, but — barring calling in “sick” — getting there can be a challenge.

Luckily, the series is expanding. In addition to the weekly lunchtime entertainment, there will also be monthly performances at night, starting Oct. 10.

The daytime shows still sound worth the mid-afternoon diversion, with such names as Happenstance Theater, which will perform “Cabaret Macabre” in October, and puppet masters-turned-Fringe Festival favorite Pointless Theatre Company in January. But the evenings seem equally stellar.

First up is Grammy-nominated musician Christylez Bacon, and the subsequent months promise Taffety Punk doing “The Rape of Lucrece” and delightful folk duo The Sweater Set.

Kicking off at 5:30 p.m., the performances admittedly start on the early side for us workaholics, but the shows sound like they will be worth the advance planning. And if you can swing it, get there a little early to enjoy a drink at Harman’s Forum bar.
