This is Spinal Tap - "This One Goes to Eleven"

Today, we present episode 29: This is Spinal Tap is arguably the best rockumentary, mockumentary, shockumentary...  You know what, it's a damned good movie!  Rob Reiner directs Michael McKean, Christopher Guest, and Harry Shearer in this masterpiece of comedy and wit.

For 1984, this film was ahead of it's time.  Famously, people who saw the movie later told Rob Reiner that he should have picked a more well-known band for his documentary!
