"Fire on High"

I listened to Face the Music to-day, and in the early alternative mix of the introduction to "Fire on High" (included as a bonus track), I discovered a quotation of "Pop Goes the Weasel."  It's a bit off-kilter, in keeping with the feeling of the track.  It's starts at about 2:38 (panned a bit to the left), and I think it's played in the upper register of a cello.

I don't think that part of the track made it into the final version though.  Only the first minute and a half are used before there's an edit into an-other section.  Still, I felt it worth noting.

"Nellie Takes Her Bow"

Jeff Lynne's ELO posted in various places that to-day's the 46th anniversary of the release of the first ELO album:

#FlashbackFriday: On this day, 46 years ago, the first ELO album was released. Recorded at the old Philips Studios in Marble Arch, London, the album features the very first ELO single, "10538 Overture."

I listened to the album and noticed a small thing about "Nellie Takes Her Bow" (I also figured out the French horn part at the end because it's only a handful of notes).  The "world" in the lines "Just a lonely girl / That could not face a broken world" isn't sung with a single syllable like it is when spoken.  I think it's actually sung to three notes: there's an initial note and then a glissando from one note to an-other.  Whatever the specifics, the note is sung with a melisma, so the "broken" quality mentioned in the lyric is also demonstrated in the music.
