Though Boston's new ice show is not spectacular, it has a good stock of the principal necessities of this brand of entertainment--graceful, unrestrained skating, colorful chorus numbers, and plenty of unsubtle comedy. Unless you have a strong prejudice against watching people fool around on ice, an evening at the Center Theater will be pleasant, if uneventful.

To be sure, there are bad moments. One dance that is meant to take place in a beauty parlor involves nine (not ten) young ladies costumed as fingernails performing a rather vapid series of body movements. But luckily the tempo is fast, and in a few minutes the girls are out there again doing a delightful waltz and jitterbug act. Then a few minutes more, and they're in a dazzling outdoor scene that has a spontaneity seldom seen in professional ice performances.

The producers of "Everything's On Ice" made a mistake when they built the show around a plot. The completely uninteresting story, known only to diligent program-readers, ties the performers down, though the comedians get around the restriction, simply by doing what they feel like. Smacking of vaudeville, the comedy includes a couple of female impersonation acts that the Watch and Ward evidently hasn't seen yet.

The effortless skating of Guy Owen and Maribel Vinson will probably satisfy ice purists. Stunts purely difficult, but lacking any sort of entertainment value, are kept to a bare minimum. Perhaps the hardest stunt, and certainly the most unsuccessful, is the attempt to dub in music from off-stage while the performers are going through an intricate dance, and apparently a crisis in the plot. There is little original music; most of the songs come from old musical comedies, and are supposed to fit the current situation in the story. While there is something definitely second-rate about this, "Everything's On Ice" saves itself by good skating and its never-flagging speed.
