The non-release of "Eight Days A Week" sparked some complaints from fans in the UK, who as it turned out, had to wait almost five months after the release of "I Feel Fine" for another Beatles single. Brian Epstein addressed these complaints in an interview with Billboard magazine:
"I think that the Beatles produce as many records as most artists on average. The reason why more people are asking for more records is that there is obviously a greater demand for Beatles' material. In my experience many artists have been damaged by over-exposure on record."
"Eight Days A Week" was released on February 15th, 1965 in the U.S. "I Don't Want To Spoil The Party" was on the flip-side. It became the number-one single in America on March 13, 1965 and remained number one for 2 weeks. It was their 7th number one single in the one-year period since their debut single on Capitol records, "I Want To Hold Your Hand" reached the number-one slot.
"Eight Days A Week" superceded "My Girl" by the Temptations and stepped aside for "Stop! In The Name Of Love" by the Supremes.
