The career of the British Invasion pop group Herman's Hermits was in full, fan-shrieking, disc-selling orbit when their first top-billed movie came to theaters, so maybe it's only natural to think NASA would want to name a rocket after them. Well, at least that's what's at stake in this 1966 romp that has the five lads on a U.S. tour, where they're mobbed by various birds - and secretly monitored by a nerdy scientist to determine if they are rocket worthy. Yes, Hold On! Is not so much about making sense as it is about having fun. A double fistful of Hermits' songs (including the Top-10 hits a Must to Avoid and Leaning on the Lamp Post) adds to the good times. Shelley Fabares, no stranger to the charts with 1962's Johnny Angel, costars.
