My guitar teacher [he’s the one about to fall into the audience] started teaching me A Hard Day’s Night a couple of weeks ago. He didn’t tell me whether it opens with Gm7 add 11 or G llsus 4th. He just told me to stop fussing about the details, enjoy it, and wobble my head about from side to side when I go “ooooh” at the end of the third chorus. What a dude.
