The Beatles began recording Eight Days A Week on October 6, 1964.
It was unique in a couple respects:
- The song starts with a fade-in, the first time that technique was used to begin a pop song.
- It was the first British single to be a #1 hit in the U.S. and not chart in its own country.
It was originally recorded for the Beatles For Sale album and never released as a single in Britain.
February 20, 1965 the single made its Billboard chart debut. Three weeks later, Eight Days A Week topped the charts. It was The Beatles 7th number one hit in America.
