Minnie Ripperton - "Lovin' You"

There is a hit song that featured the sounds of chirping birds throughout, the heady lyrics "La la la la la la, dood'n dood'n doo doo", and a sound from a woman that can only be described as "just about to climax".  Put all that garbage together and you get Minnie Ripperton's "Lovin' You"--a #1 song from 1975.  What were the folks smoking in 1975???
