Maine's cornucopia of arts; Jack Jones; swing-dancing in Boston; Crooner, clarinet, and Clooney

Woody Herman and his ''Thunderin' Herd'' provide all the nostalgia one needs in the current North Shore Music Theatre program. The sweet sounds of Woody's clarinet take audiences back over 44 years of jazz. Add 30 minutes of Rosemary Clooney - with additional oldies but goodies (including her trademark ''Come On-a My house'' - and it's a full evening of deja vu. Woody taps, Rosie bounces around, but a main ingredient would still be missing for a top evening.

Fortunately, there's Jack Jones. It's difficult for this audience to realize that Alan (Donkey Serenade) Jones and Irene Hervey's boy is now a veteran of 25 years. Don't let his casual, hang-loose manner throw you off. Jack Jones has one of the richest voices around. And his repertoire - from Gershwin to Michel Legrand - shows off his power, clarity, and wide range. ''Wives and Lovers,'' ''Send in the Clowns,'' and ''What Are You Doing the Rest of My Life?'' are still great audience-pleasers.

North Shore Music Theatre - up Route 128 in Beverly - is a relaxing summer evening. Come early. There's a good buffet in the Terrace Restaurant. and the craft shop is a treat. Herman-Clooney-Jones are on tap through Friday.
