Megadeth Demo Dub

This is what I believe to be a very early dub of Megadeth's three song demo, "Last Rites/Loved to Death." This item belonged to a friend of mine who obtained it from a well know figure in the music industry back around 2001 or so. What makes me think that this item is not in fact the real deal is the how it has a recording of an early Megadeth show on it as well. Imagine No Life Til Leather and Live Metal Up Your Ass being mixed onto one tape, that's the same premise; there are songs on both sides.

Side 2 - SAN FRANCISCO, CA (4-18-84 at the Stone, this was Kerry King's fifth and final show with the band). I also have a flyer pictured in my gallery from this show as well.
