I get tired sometimes. This leads to my becoming irritable and, before too long, mildly morose. Experience has taught me to force myself to seek something to lift my soul out of the gloom, something that will instantly deliver a moment of pure happiness. Tonight that something is the beautiful, soaring Intermezzo from Cavalleria Rusticana by Mascagni. I think I’d heard it before but it first made its impact on me when I heard it in the excellent film Raging Bull.
