BECKET - In “Fräulein Maria,’’ David Parker lets out a giddy “wheee!’’ at the end of his duet with Scott Lowe, and it pretty much sums up the audience’s feeling. Parker’s unabashedly girlish exclamation suits his portrayal of Liesl, the eldest Von Trapp daughter - just one reinvention of many in Doug Elkins’s hilarious and loving tribute to the iconic movie “The Sound of Music.’’
The hour-plus work has developed a loyal following over the past few years in the cabaret atmosphere of Joe’s Pub in Manhattan, but at Jacob’s Pillow it proves irresistible even in the more traditional theater setting. The lovable, tuxedoed Michael Preston, as emcee, gets things rolling with an audience singalong. Within moments, without cues or a cheat sheet, we were all singing “Do-Re-Mi’’ as if we’d been rehearsing our whole lives.
