This Is Spinal Tap (1984).
Iāve not seen this since the 90s. I bought from Apple when it was on sale months ago. But I only got around to watching it tonight for obvious sad reasons.
This movie is just so damn funny. I had a cat on my lap watching it and when Nigel tells the name of his lovely piano-instrumental I laughed so loud she jumped, and looked at me visibly angry.
