Halfway through "Always Remember Us This Way", a view of Ally at the piano from the side (the audience's perspective), on the big screen at the back of the stage it shows her singing vocals while for several seconds she is not.
When Jackson is about to see Ally perform in the drag bar, he asks if she's really singing or is it 'one of them karaoke things' , but in karaoke the person is actually singing - even if it's bad! He probably meant to say 'one of them lip syncing things'.
Jack and Ally are walking toward each other in a gas station parking lot during the trip to Arizona. Ally is wearing a blouse when the shot starts, but when they meet and embrace, she's wearing a leather jacket.
When Bobby takes Jack home from the rehab, they arrive to the house, Jack tells him he idolized him, then shuts the door and walks away - Bobby immediately backs up the car and leaves. Moments later, when Jack enters the house, he is carrying a suitcase and his guitar, none of which has he taken out of the truck.
When Ally steps to the microphone onstage at the tribute performance, she is lit in a spotlight shining down from her left. In the closeups of her face, however, the shadows of her chin and the microphone are on her left, indicating the lights are now shining down from the right.
When Jack and Ally arrive in their hotel room, Jack drops his key card on the floor as he stumbles into the hallway table. He turns and moves into the next room as Ally goes into the bathroom and shuts the door. When she opens the door, the key card is gone.
During dance rehearsal before the Saturday Night Live appearance, Ally, dancing in front of a mirror, is holding a water bottle while she sings. When the camera swings around in front of her, the bottle is gone.
When we are looking into the control room at Saturday Night Live, we are seeing monitors which presumably show us what is being broadcast. When the musical guest is appearing on SNL, however, a photo of the musical guest is shown coming out of commercial before going to the live broadcast.
Bobby tells Ally that Jack just kept saying, "I love how she sees 'em, Bobby." But Bobby quit before Ally's first concert touring with Jack, and at their reunion at Saturday Night Live it appears they did not keep in touch. By the time they were reunited, Jack was describing her musical choices as "embarrassing."
When Ally performs at the I Heart Radio showcase, this is the first time she's performed this song in front of an audience. But when she reaches the chorus for the first time, two women in the front row to Ally's left are singing along, most noticeably a woman in a red halter top.
