All I’m asking for is perfection,” goes a line from the title song of the new revue “Make Me a Song,” handily encapsulating the work ethic and personality of composer-lyricist William Finn. The songwriter is notably irascible, but this songfest should leave him tickled. In a word, it’s Finntastic. Finn has always worn his heart — and his music — on his sleeve.

His songs come mostly in two varieties: idiosyncratic and often raucous comedy numbers on one hand, and soaring ballads that pull at the heartstrings on the other. Both types are in evidence here, with the serious songs giving the evening an emotional pull that might surprise some audiences. Amidst bounteous laughter, Finn’s singers bring you to tears with “Unlikely Lovers” and “Anytime (I Am There),” two of the most affecting songs to come from recent musical theater.
