Yes, the appearance of the Monkees — Micky Dolenz, Davy Jones and Peter Tork — at Aronoff Center for the Arts on Saturday night could be considered merely an oldies/nostalgia show. But it is much more. The group, augmented by a veritable orchestra of musicians, will play the hit songs first recorded when their stylish, Beatles-influenced 1966-1968 television show was the rage — "I'm a Believer," "Last Trains to Clarksville," "Daydream Believer," "Words" and more were smashes.
