Stevie Ray Vaughn unplugged?

Does this exist? I remember seeing him play unplugged before but I don't recall seeing this on a CD.
Yeah, he did 3 tracks( Testify, Pride & Joy, Life Without You) in an episode with Joe Satriani back in 1990, Recorded 1/30/90 at National Video Center - New York City.

A couple of the tracks (Pride & Joy, Without You) aapear on the "MTV Uplugged: Classic Moments (1990)" DVD. Others appear on a couple of his box sets.
