Keytar Bear, one of Boston’s most lovable street musicians, is popping up at the Painted Burro for their Pajama Party Karaoke. You’ve likely seen him all over the Boston area, jamming on his keyboard near subway and train stops. And on Tuesday, November 15th, he’s headed to the Davis Square spot for a fun night of boozy margaritas, tasty tacos, and electric tunes. Slip into something comfortable (seriously, pajamas and sleepytime attire is encouraged) and dance the night away in the Painted Burro lounge. Come early for dinner (you can reserve a table via the Painted Burro website), then head over to the party, which starts at 9:00pm.
