If you’re a Modern Lovers fan, you already own and love their definitive album (The Modern Lovers, recorded in 1973 and originally released in 1976). During the time of that album’s troubled production, several live performances in Boston and Berkeley were caught on tape, resulting in this kookily charming collection of live versions of many of that seminal album’s tracks.  The sound is rough and tumble and some moments are brighter than others, but even audiophiles can be won over by sheer Modern Lovers magic. While the studio versions of these songs stand well enough on their own, here the raw, youthful energy of Jonathan Richman and his band breaks through the ennui (or is it bemusement?) of their live audience, showing once again why songs like “She Cracked” and “Roadrunner” are often pointed to as pure pre-punk punk.  Additional tracks include the pleading “Dance with Me” (where Richman hilariously chastises a would-be girlfriend for wasting her time listening to Santana records in her dorm), a top-notch cover of the Velvet Underground’s “Foggy Notion,” and the romantic “A Plea for Tenderness.”  A crowning moment may be Richman’s lyrical exhortations directing a crowd of Harvard students to face the sexual tension in the air on “The Mixer (Men and Women Together).”   (NOTE: This is the U.S. version of this collection; an import version was released in 2005 on France’s Last Call Records, entitled Live at the Longbranch and More, with a slightly different track list.)
