Composer Marvin Hamlisch, who died last August at 68, racked up four Emmys, four Grammys, three Oscars, and a Tony, not to mention a Pulitzer Prize for “A Chorus Line.’’ Especially in the 1970s, Hamlisch seemed to be everywhere.
Yet his fixed address was too often the middle of the road. You could seldom call Hamlisch’s music truly inspired. The temptation always lying in wait for the gifted and prolific is to spread themselves too thin, and Hamlisch composed too many bland movie soundtrack numbers, too many generic love ballads. That quality of creative dilution comes through in “They’re Playing His Songs: The Music of Marvin Hamlisch,’’ a pleasant but largely electricity-free revue at the Cape Playhouse, conceived and directed by David Zippel.
