"God Gave Rock and Roll to You"

I listened to Encore yester-day and noticed a small feature in "God Gave Rock and Roll to You."  In Rod's line "To ev'ry boy he gave a song to be sung" in the middle section, the phrase "ev'ry boy" is sung to notes of all different pitches (F# G# A), giving a sense of number.  This is also in the studio version (on In Deep).

In comparing the two recordings, I discovered that the live version on Encore lacks the repeated line "To ev'ry boy he gave a song" in the coda.  The same feature is there, but the melody is different, so the pitches to which "ev'ry boy" is sung are F# G A (I think they're also an octave higher than those in the middle section).
