Regarding the signal chain, I recorded the vocals with a cheap mic, a Behringer B1, through my Alesis multimix8FX USB soundcard directly into Reaper. The first effect on the chain is Reacomp, with subtle settings (3ms attack and a compression ratio of 3:1). Then I'm using Reaper's native reverb (Reaverb) with the free Pipeline Audio Impulse Response files, wich is a killer combination IMHO. I used specifically the Hall 1-19.wav file from the Pipeline pack, adjusting just the "wet" parameter to my taste.

PS: To me, this is a great composition from Stevie, it's just that it was created on the wrong era (the 80s) and its arrangments are heavily dated; if it was created on the "Songs in the Key of Life" era, things would be very different. Anyway, I'm a great fan of Stevie, so maybe I'm not being objetive
