In this two-man show, the Australian actor John R. Waters (accompanied by the pianist Stewart D'Arrietta) wisely doesn't attempt a complete impersonation. There are no glasses or beard or mop top here, just an evocative approximation of the voice and a deeply felt reflection of the man. The show amply covers spirited rockers, but much of it explores the darker depths that so distinguished Lennon from the sunnier Paul McCartney. The darkest corners - Lennon's early abusive romantic relationships and his heroin use - are avoided. (No "Cold Turkey" here.) But the Beatle fanatics sure to see this show won't mind (1:30).
