Despite a couple of British Top Ten hits in 1964-1965, the Rockin' Berries made no dent in the U.S. market at the height of the British Invasion. Much of the Berries' output reflected the lighter pop/rock face of the British beat boom, emphasizing catchy, carefully constructed tunes supplied by British and American songwriters, with high harmonies indebted to the Four Seasons and the Beach Boys. The Berries wrote little of their own material, and this, combined with the wimpiness of some of their recordings, doomed them to little recognition, and little critical respect, even among British Invasion aficionados. For what they were, however, their best pop/rock outings were pretty respectable. A career strategy that put an eye on the "all-around entertainer" niche, however, led them to record many comedy numbers that have dated excruciatingly badly, and also ensured that they were denied artistic credibility and would fall out of the British charts after the mid-'60s.
