"Fixing a Hole"

When I listened to the second disc of the 2 CD Anniversary Edition of Sgt. Pepper a few days ago, I noticed something about "Fixing a Hole."  The version on the second disc is a different take from the one that ended up on the completed album, but both have this same feature: the "go" in the line "Where it will go" is sung with a glissando (Ab down to F), which gives a musical impression of "go[ing]."
