Argent's "Pleasure"

I just listened to a compilation album of Argent (Greatest: The Singles Collection).  I'd previously noticed the melisma'd "rain" in the line "Falling rain to cool my aching face" in "Pleasure," but I'd failed to realize that - because the notes are descending (F# E D# C# B, I think) - the melisma helps to convey that the rain is falling.
