"Sun King"

When I listened to Abbey Road on the 50th anniversary of its release, I also realized something about the sound effects at the beginning of "Sun King."  (According to Mark Lewisohn's The Complete Beatles Recording Sessions [p. 185, the entry for 5 August 1969], these were compiled by Paul.)

One of the sounds is chirping crickets, and I think this might be a subtle reference to Buddy Holly and the Crickets, who were an influence on the Beatles.  It's also worth mentioning that (although by accident) Holly's "I'm Gonna Love You Too" features the sound of a cricket at the very end.

"I Want You (She's So Heavy)"

I listened to Abbey Road yester-day because it was the 50th anniversary of its release, and I noticed a small thing about "I Want You (She's So Heavy)."  "Bad" in the recurring line "I want you so bad" is sung with a variety of melismas, musically giving a sense of degree.

"I Got a Woman"

I've been listening to Ray Charles lately, and to-day I noticed something in "I Got a Woman" that's also present in the live versions the Beatles did for the BBC.  "All day and night" in the first line of the bridge ("She's there to love me all day and night") is a merism.

"Getting Better"

"Getting Better" and "Within You Without You" were mentioned in a Jeopardy! clue yester-day (Sgt. Pepper's Lonely Hearts Club Band was the answer), so I listened to the album and - coincidentally - noticed something about "Getting Better."  In the line "It's getting better all the time," "time" is sung with a melisma (F E F).  I think this gives something of an impression of that "all," but I'm not sure if it's used in quite that sense.

"All My Loving"

I listened to the second disc of Live at the BBC yester-day and noticed a small thing in "All My Loving."  "Day" in the line "I'll write home ev'ry day" is sung with a melisma (C# G#), giving a sense of number, almost as if it's emphasizing that "ev'ry."
