We see Jane playing the piano on her own in a room. She has her socks on. Nick enters the room. They chat a bit and he leaves. Jane is now playing the piano with shoes on.
When Andy is browsing the VHS cassette tapes at Jasper's house, you can see one cassette label texted "Sibelius Hall". The Sibelius Hall is a concert hall in Lahti, Finland. It was built in the end of the 90's and completed in the year 2000. Andy's mom Jane could not have played the piano there in the 80's.
When Andy and Michael are walking along the pier in San Fransisco, a map of Sydney, Australia where the scene was filmed can be seen briefly in the background. The Darling Harbour Ferris Wheel can also be seen in this scene.
