So this is the Song Brazil by The Real Tuesday Weld, I believe it is a covered song
Bares and Russel - Brazil

But I cannot find any info on Bares and Russel or the song whether its the original or the cover.

I really like The Real Tuesday Welds version of the song and have been trying to figure it out for awhile but the chords used are so distant to me, this type of music isn't my best area for tabbing, I know the melodic whistle but these jazzy chords are unknown to me, I could really use some help deciphering the song into tab and chord.
I don't care who gets credit for tabbing or whatever lets just get this done!
