I always like posting videos of Broadway musicals performed in different countries around the world. This one is a scene and song from Man of La Mancha done in 1974 by the original cast in Chile. Or rather, El Hombre de la Mancha. The show starred Jose Maria Langlais, with Alicia Quiroga as Aldonza/Dulcinea, and Herman Gallardo as Don Quixote's manservant, Sancho Panza.
I've song some clips from the show in the past. This one is the song, "I Like Him," which features Quiroga and Gallardo. The scene leading up to it is Sancho Panza delivering a missive from his master to be sung to the scullery maid Aldonzo, who Quixote in his madness sees as the virtuous maiden 'Dulcinea.' She repeatedly ridicules Sancho, until finally asking him, "Why do you follow this man??" Why stay with him??? He's totally stumped -- and finally the only answer he realizes is the truth is that, as he sings, "I like him. I really like him."
If you want to jump right to the song, it starts around the 4:15 mark.
