Looking for these HBB shows

[Headbangers Ball]

I got some new DVD's in recently and they had some clips from HBB on them which is cool but they're not full shows. One was a Vinnie Vincent compilation that had clips of Mark Slaughter and Vinnie Vincent hosting HBB in 1988. And another was a Lita Ford compilation DVD with clips of her hosting HBB in 1988 and 1990.
So, I'm looking for the following complete Headbangers Ball shows with all the videos and commercials if possible...
Lita Ford hosting ?/??/88
Mark Slaughter and Vinnie Vincent hosting ?/??/88
Lita Ford hosting 6/2/90
If you have any of these get in touch with me
