“She’s a Rainbow” - Rolling Stones…Nothing like a nice, bucolic tune about a wonderful girl that ends with horror movie soundtrack violins.
Rambling, almost Bartok-like piano at the end of Bowie’s “Aladdin Sane” - even more spidery-like in the “David Live” version.
About three-quarters through what would have been my favourite Black Sabbath tune - “Symptom of the Universe” - they break into something that would have been much more at home on the Doobies’ “What Were Once Vices and Now Habits” album, which has a couple half-decent songs, itself, but definitely not capping off SOTU.
About the only thing I can tolerate about April Wine’s “I Like to Rock” (and it’s kinda neat actually) is how it fades out, deftly intertwining the guitar lines from “Satisfaction” and “Day Tripper”.
“Long, Long, Long” - Beatles - keyboards at the end go way up in the mix, with odd howling. Interesting hearing that for the first time when you’re a five-year-old ('69) sitting almost fetal-like in front of the old Viking console and then appropriately freak-out responding by pen-scratching actually several Beatles albums, which were kept around as a friendly reminder. A year or so earlier an older sister freaked at the “I buried Paul” coda on “Strawberry Fields”.
So yeah, if you have any traumatizing backstory to any examples, feel free to share.
