My Fair Lady Had George Bernard Shaw lived a little longer, that rain in Spain may never have fallen mainly on the plain, or at least it might not have fallen in time to music. Shaw, a rather cranky sort even on the best days, hadn't liked what a musical adaptor did to his Arms and the Man, and so opposed any attempt to turn his Pygmalion into a song and dance extravaganza. But his heirs were less picky, and so in 1956, we got the tale of Eliza Doolittle and the pompous Professor Henry Higgins set to the songs of Lerner and Loewe. The 40th anniversary production of the show previews tonight through Saturday matinee, with the official opening Saturday evening. Runs through October 27. 8 p.m. Music Hall, 810 Bagby, (800) 766-6048. $15-$48.
