Here's a photo from the great collection of Judith Supple Hadlock of Micky and Davy on horseback while visiting Providence, Rhode Island for a performance at the Providence Performing Arts Center in April 2002.
In 1988, after two frenzied years on the road and in the studio, The Monkees maintained a relatively low profile. Micky, Davy, and Peter eventually toured Australia late that year, but beyond that, the only other group public appearance in '88 was at a Monkees convention in Chicago, Illinois in August. The trio were guests at the gathering, and Peter played a solo show at the Vic Theatre on August 20 to coincide with it. This article, from an early 1989 issue of the UK fanzine Band 6, provides an overview of the event.
