CAMBRIDGE - “Lord help the mister who comes between me and my sister / And Lord help the sister who comes between me and my man.’’ That’s the bit from Irving Berlin’s “Sisters’’ that prompted the title of the new “autobiographical fiction’’ from David Parker and the Bang Group, “Misters and Sisters: A Love Story in Song and Dance.’’ Last Wednesday, Summer Stages Dance brought the show to Oberon, where there will be a second performance tomorrow. Inspired by and dedicated to Parker’s father, the late Boston crime novelist Robert B. Parker, this 70-minute cabaret show affords Parker and his professional partner of 21 years, Jeffrey Kazin, the opportunity to play both misters and sisters as they celebrate their love of song and dance and their affection for each other in a dizzying display of terpsichorean fireworks.
