Minnie Riperton is pretty much universally known for her #1 hit "Lovin' You", but quite honestly, I prefer some of her other, lesser-known songs. Sadly, Ms. Riperton died, way too soon, in 1979. A final album, Love Lives Forever, came out in 1980, featuring some tracks Ms. Riperton had recorded before, along with other tracks contributed by several artists as a tribute to her.
"Here We Go" was the first single released from Love Lives Forever, and as far as I can tell, it hit the top ten of what was then called the Hot Soul Singles chart. Check out how Ms. Riperton is able to enunciate "here we go" clearly in the "whistle register".
And as usual in this feature, no station in town has ever played this as long as I've been here, to the best of my knowledge.
(Note: most information in "forgotten songs" entries comes from the always-reliable Wikipedia; as such, its veracity may be questionable.)
