From the wiki: “‘Over and Over’ was written by Robert James Byrd and was recorded by him in 1958 using his stage name, Bobby Day (a name he earlier used when a member of the original ‘Bob & Earl’ duo until parting ways in 1957). Day’s version entered the Billboard Hot 100 in 1958, first as the B-side to the hit single ‘Rockin’ Robin’ and, soon after, as an A-side, the same week a version of the same song by Thurston Harris (who had covered Day’s ‘Little Bitty Pretty One‘ the previous year with chart success) entered the chart. Day’s version would reach #41 on the Hot 100 but would top the R&B chart; Harris’ single peaked on the Hot 100 at #96.
“In late 1964, the Righteous Brothers recorded ‘Over and Over’ for inclusion on their Phil Spector-produced album You’ve Lost That Lovin’ Feelin’, released in early 1965, but it was not released as a single.
“In 1965, the most successful recording of ‘Over and Over’ was released by The Dave Clark Five, one of the early British Invasion bands of the mid-1960s. Despite the record’s success in the United States (US #1) and the overall popularity of the group on both sides of the Atlantic, the single only reached #45 on the UK Singles chart.”
