One of my abiding memories of my dad was being allowed to stay up late one night with him (after mum had already gone to bed) watching Dr. Strangelove.
We both found that final scene set to this song hilarious, both with tears in our eyes laughing so much. Re-watching never captures the moment in the same way, but it does bring back the memory.
There's something very, very powerful in these unexpected shared moments of childhood.
Now I'm missing my dad again :(
