I do know thats not david's last boot. I could be wrong but I think the last boot is wild in the stadium from sept. 1, 1984. It is available here to download if you search through the vh section. Hope this helps.
Rhoads, Van Halen, Lee, DeMartini/Crosby, Becker.
Dave's last show with the band is listed as September 2, 1984 at the Monsters Of Rock Festival in Nuremberg, Germany. A boot titled Dave's Last Stand claims to feature a B-quality audience recording of this show. Happy hunting...
