Beatles observation

Here's a Beatles observation for you: anytime there is non-lyrical melodious filler, you can be sure it's Paul, and never John. Any whistling, or "doo do doo", or humming--always Paul. I don't think there's even one instance of John doing this (or George, but I'm not as sure about that).

Examples:

• Mother Nature's Son ("doo do doo do doo do...")
• Your Mother Should Know ("da da da..")
  
• Fool On the Hill (instrumental verse; "oh oh oh ohhhhhh round round round...")
• Hey Jude ("na na na na na na naaaaaaaaaaaa...")
• Rockey Raccoon ("da da dada da daaaa"; "do doo do do dooo do")
• Honey Pie (instrumental segment/"I like this kinda, kinda muuuuuusic"; "oh ho ho ho ho hoo ho")
• I Will (humming)

I'm sure there's lot of other examples.

Anyway, if someone knows of a John song (or John part of a song) with similar melodious filler, I'd like to hear it.

Oh, Yoko's alright

John Lennon, sonofabitch

Stumbled across this snippet of the John Lennon interviews, which must have been in like 1970 or so when he and Paul were at the height of their schoolyard taunting phase. It's pretty great.
