The Dave Clark Five had 12 Top 40 hits in the UK between 1964 and 1967, and 17 records in the Top 40 of the US "Billboard" chart. Their cover of Bobby Day's "Over and Over" went to No. 1 in the US on the "Billboard" Hot 100 on Christmas Day 1965, despite less impressive sales in the UK (it peaked at No. 45 on the UK Singles Chart). They made 18 appearances on "The Ed Sullivan Show" – more than any British Invasion group.
