"Ev'rybody's Gonna Be Happy" is a song by Ray Davies, released as a UK single by the Kinks in 1965. As the follow-up to the number-one hit "Tired of Waiting for You", and having their previous three singles all chart among the top two, it was less successful, reaching number 17. It broke a run of what would have been thirteen consecutive top-ten singles in the UK. The song was written as a musical experiment, rather than as an intended single, according to Davies in an interview, where he also claimed that the demo became the master version of it.
