No, having three song cues in the film, does not make LBT movies musicals.
I'm sure you all know what musicals are - many songs, ususally one or two major dance numbers that branch off from one of the songs. That's as simple as they get.
I've followed many of them, and have my list of favorites, and I've found that I often care for the music more than the plot line. I don't think I've ever enjoyed the plot more than the music.
1. The Sound of Music
2. The King and I
3. The Wizard of Oz (it's major dance scene, The Jitterbug was cut from the film)
4. Chicago
5. Oklahoma!
6. Anything Goes
7. Grease (Now can you hand jive?)
8. Newsies
9. The Music Man
10. Annie
11. Singing in the Rain
I'm bound to see many more. I'll probably watch a few more we have on tape that I haven't really watched yet - A Chorus Line, and Bye Bye Birdie.
