The single was released on EMI's
Parlophone label in Britain (as Parlophone R 5389) on 3 December 1965, the same day as
Rubber Soul. On the front page of its issue published the previous day,
Melody Maker confirmed the release dates as well as the dates for the promos' airing on British TV and for the band's
UK tour; the editors called the week ahead "National Beatles Week". In the United States,
Capitol Records issued the single on 6 December (as Capitol 5555). The release coincided with speculation in the UK press that the Beatles' superiority in the pop world since 1963 might be coming to an end, given the customary two or three years that most acts could expect to remain at the peak of their popularity. In addition, after receiving their
MBEs for services to the national economy in October, the group were temporarily perceived as being part of
the establishment.
Cash Boxs reviewer predicted that the Beatles would "quickly trip the [US] charts fantastic for the umpteenth time" with "We Can Work It Out" and described "Day Tripper" as a "hard-pounding, raunchy ode all about a gal who is somewhat of a tease". Derek Johnson of the
NME said that "Day Tripper" "generates plenty of excitement" but it was "not one of the boys' strongest melodically", and "the other side is much more startling in conception." In his role as guest reviewer for
Melody Maker,
the Animals'
Eric Burdon said he preferred "Day Tripper" and especially admired Harrison's guitar contributions, saying that rather than musical prowess, "It's what he does and when he does it." Burdon also wrote: "It's fantastic that every Beatles record that comes out gets knocked, then two or three days after everybody likes it. But I like this immediately." "We Can Work It Out" / "Day Tripper" entered the
UK Singles Chart (at the time, the
Record Retailer chart) on 15 December, at number 2. Although three singles had previously entered at number
one, "We Can Work It Out" / "Day Tripper" was the first ever
UK Singles Chart debut at number 2. It would then hold the top position for five consecutive weeks. The single also failed to top the national chart published by
Melody Maker in its first week – marking the first occasion since December 1963 that a new Beatles single had not immediately entered at number 1. Although it was an immediate number 1 on the
NMEs chart, the
Daily Mirror and
Daily Express newspapers both published articles highlighting the apparent decline. The record was the Beatles' ninth consecutive chart-topping single in
Record Retailer and their tenth on the country's other charts, and for the third year in succession they had the
Christmas number 1 hit as well as the top-selling album. "We Can Work It Out" / "Day Tripper" was also the band's fastest-selling single in the UK since "
Can't Buy Me Love" in 1964. Alan Smith, the reporter assigned to cover the Beatles' UK tour for the
NME, commented: "Anyone who says they're finished – particularly with 'Day Tripper' / 'We Can Work It Out' at No. 1 in the
NME Chart in its first week – must be out of his head!" In the US, both songs entered the
Billboard Hot 100 on the week ending 18 December. In early 1966, "We Can Work It Out" spent three non-consecutive weeks at number 1, while "Day Tripper" peaked at number 5. The single was certified gold by the
Recording Industry Association of America, for sales of 1 million or over, on 6 January. The record topped charts in many other countries around the world, although "We Can Work It Out" was usually the favoured side. ==Live performances==
