" Rain " is a song by the English rock band the Beatles first released in May 1966 as the B-side of the " Paperback Writer " single. Both songs were recorded during the sessions for the album Revolver although neither appears on that album.
Three promotional films were made for the song "Rain".  These videos, along with other Beatles videos at the time, sparked George Harrison to say during the Beatles Anthology , "So I suppose, in a way, we invented MTV." 
Rooting through record bins one day at the late, great Central Records in Cambridge, Mass., I came upon a stash of Yoko Ono albums and asked the sagely aging raver behind the counter what they were like. Were they song-based records or more of her avant-garde, musique concrète stuff? Were these albums enjoyable on their own accord, or just Yoko pushing the envelope for envelope pushing’s sake? Refusing to answer my question directly, the man looked down from his stool, lowered his glasses and told me, “Yoko Ono didn’t break up The Beatles—John Lennon did.”
Now that was a contrarian claim to this college kid, liberal arts education be damned. The “jealous woman breaking up the band” archetype has become so embedded in our cultural subconscious that the name “Yoko” is lobbed at any woman perceived to be threatening a band’s unity. Paul, George and Ringo also apparently agreed that no spouses were allowed in the recording studio, but John did not.
