Recorded the day after the Beatles’ Ed Sullivan debut and rushed out on Capitol Records within a month, “A Letter to the Beatles” captures a very specific moment of mid-’60s panic. The Four Preps — the West Coast group behind “26 Miles (Santa Catalina)” — watched the British Invasion threaten their own fanbase, and Stu Phillips produced their musical response in real time.

Oriole Records famously turned down the Beatles in 1962 — then rushed out this fan-song answer to “She Loves You” in 1964. Studio group The Carefrees (built by producer Reg Warburton, based on “We Love You Conrad” from Bye Bye Birdie) got a “MISS!” from UK’s Juke Box Jury, but the U.S. release hit #39 on Billboard — making it the most successful Beatles novelty record ever, and the only one to crack the Top 40.

Written and recorded on February 13, 1964, by the Holland-Dozier-Holland-Taylor team at Hitsville U.S.A., this Motown Beatlemania cash-in was slated for release on V.I.P. Records — until Berry Gordy’s team scrapped it before shipping, wary of the label’s reputation. Locked away for nearly 40 years, it finally surfaced on R. Dean Taylor’s 2001 Essential Collection, with Taylor later admitting it was made as a quick joke, not a serious hit.
