Why does the music video of "Living Next Door to Alice" by Smokie seem happy?

By | February 15, 2017

The song "Living Next Door to Alice" tells (in my opinion) a bit of a sad story. The protagonist is talking about Alice leaving, how he won't be able to see her again and won't be able to ever tell her about his feelings. Despite that sadness, in the music video, it feels like Smokie is trying to debase it by constantly smiling.

Is this just my opinion, or is the song actually not that sad?
