The Dave Clark Five (also known as "The DC5") were an English pop rock group. Their single "Glad All Over" knocked the Beatles' "I Want to Hold Your Hand" off the top of the UK singles charts in January 1964: it eventually peaked at number 6 in the United States in April 1964. They were the second group of the British Invasion on The Ed Sullivan Show, appearing in March for two weeks after the Beatles appeared three straight weeks in February 1964. For some time they were more popular in the US than in their native UK, but they had a renaissance in the UK between 1967 and 1970. The group disbanded in late 1970. On 10 March 2008, the band was inducted into the Rock and Roll Hall of Fame.
"Because" was written with the intention of being the Dave Clark Five's fifth US single, but the band's label, Epic Records, was initially resistant, believing the ballad strayed too far from the hit-making formula that had proven successful with the band's previous upbeat singles. In May 1964, the song was released in the UK as the B-side to "Can't You See That She's Mine". Clark insisted that "Because" be released as an A-side in the US, and Epic eventually agreed. The single entered the Billboard Hot 100 chart at number sixty in August, and peaked six weeks later at number three. "Because" became the band's fifth US single to sell more than one million copies. In Canada, the song reached number three on RPM magazine's singles chart.
