Here's a batch of LPs that all capitalized on pop culture phenomena.
Cleopatra, Saturday Night Fever and James Bond all had many releases riding on their coattails.
Chicago, Chico & The Man & Marty Robbins probably had less.
Hair probably has more exploitative emulators than any other movie.
However, both of my Hair related images got lost somewhere in my computer's nether regions, so I'll have to include some the next time I cover this topic!
