It is a lifelong musical journey from the dreamy innocence of “Never Never Land” to the world-weary delusion of “Something Cool.” Yet, Jane Monheit, now firmly established as one of the post-millennial jazz world’s foremost vocalists, has managed to make the trip in just eight years. In 2000, Monheit chose the sweet, escapist Peter Pan lullaby as the title tune for her debut album. Now, with The Lovers, the Dreamers and Me, her sophomore release for Concord (following 2006’s sumptuous Surrender), she is plumbing the gin-soaked escapism of the heartrending tune made famous by June Christy in 1953.
