The difficulty in reviewing Smokey's Joe's Café, the Timber Lake Playhouse's season-closing musical, doesn't lie in knowing how to start, but when to stop. A plotless assemblage of '50s and '60s rock & roll hits, bluesy love songs, and novelty tunes by composers Jerry Leiber and Mike Stoller, this jukebox revue finds its nine-person cast performing nearly three dozen numbers, and based on their presentation here, I could make a fair case for devoting 500 words to each of them.
