Per Paul after the initial intent to use the song for Timothy Leary’s campaign –

I said, ‘Let’s slow it down with a swampy bass-and-drums vibe’. I came up with a bass line, and it all flowed from there.

“Come Together” started as John Lennon’s attempt to write a song for Timothy Leary’s campaign for governor of California against Ronald Reagan, which ended when Leary was sent to prison for possession of marijuana. Lennon commented:

The thing was created in the studio. It’s gobbledygook; Come Together was an expression that Leary had come up with for his attempt at being president or whatever he wanted to be, and he asked me to write a campaign song. I tried and tried, but I couldn’t come up with one. But I came up with this, Come Together, which would’ve been no good to him – you couldn’t have a campaign song like that, right?'
