The Lemon Pipers' "Through with You"

This morning I listened to The Best of the Lemon Pipers, and I noticed something about "Through with You."  At about 7:45, the drums, which had been in the left channel, pan to the right, and the bass, which had been in the right channel, pans to the left.  The first line after that is "My world takes on a different form."  That panning illustrates that musically.
