I actually agree with singtopher's choices. If you take away lyrics and plot, you're left with visuals and a style of music.
If your friend likes more classical, lush, romantic music and has a basic understanding of the Phantom of Opera story, take him to that.
If he likes jazzy music with sexy dancers in black, take him to Chicago.
If he likes ABBA songs, which are fairly global, and a Greek island setting, take him to Mamma Mia!
