"Since the Last Goodbye"

I listened to Ammonia Avenue (with bonus tracks) yester-day and discovered something about "Since the Last Goodbye."  In the version with Eric Woolfson's guide vocal, "fly" in the line "The hours, the minutes seem to fly" is sung with a melisma (D# C# A#), musically giving a sense of the passage of time.  In the final version, however, this feature isn't present.
