Name that tune (or at least the artist), Vol. 1

I will play a song where I have removed the vocals and other distinguishing instruments found at the beginning of a song. As the song progresses additional instruments will be added. Your job is name the tune, or at least the artist or any other distinguishing bit about the sound (remember this is for fun so score yourself appropriately).

Correct answers during the early stage = 1 Point.

Correct answers after new instruments or familiar melody appears = 1/2 Point.

Example: I will play the instrumental and pause it after x seconds (in this example it is 8 seconds). If you have the correct answer, you get one point.

I will then unpause and let it run for up to a minute or so. If you get the correct answer at this point, you get one-half point.

Full song: "Proud Mary"
