My God some of you are spectacularly missing the point!
It’s about fathers reconnecting with their children (a son especially). The son bought the record for his dad, which takes him back to his younger days - and remembering how much he loves his son, and how close they used to be. The gift and the (now teenage) son seeing his dad enjoying it, bring them back together again. Strengthening the bond between them.
I thought it was brilliant. Managed to be moving without any of the schmaltzy Christmas stuff we’ve seen before.
