Steely Dan ~ Only a fool would say that with lyrics on screen

’Only a fool would say that’ from ’Cant buy a thrill’ has two references to John Lennon, or at least the Beatles: “imagine“ and “brown shoes“ (although Old Brown Shoe was written by George Harrison, but who shared Lennon’s hippie utopia mindset), as well as references deriding his vision in Imagine of everyone living freely and “You may say I’m a dreamer“ in the line “A man with a dream“. I think the gun reference - “unhand that gun begone, there’s no one to fire it upon“ replies to pointing fingers at others (as pointing at others tends to look like the gun position kids use when playing cops and robbers) and that there’s no one who is deserving of blame (having the accusation targeted at them). Thus the “if he’s holding it high, he’s telling a lie“ means if he’s pointing it at those high up, especially someone who would hold a “bed-in“ protest at the Amsterdam Hilton, like Lennon,
