Do you know this weird Beatles song?

Long story short, I was in charge of the music library for the radio station at my college, and before we revamped the entire station and gave everything a facelift, the previous music directors had some. . .well. . .eccentric music (AKA a 15 minutes long track of someone banging on random piano keys). So I cleaned it up and whatknot, but there was still this one song people were like “WTF?” about and apparently it’s a Beatles song. But a really, really, really, really weird Beatles song. Like they must have been high. I can’t recall the lyrics, but it was the same verse over and over and over. I think it was “Don’t be long now” or something like that, and I never could find it, probably because I misheard the lyrics.
