mark stone demo's?

[paulscape]

Ive heard most of the 74-77 gazzari's and starwood early bootlegs and demo's. Wondering if there are any even earlier recordings like you can hear in the VH1 van halen behind the scenes video. Its hard to make ut from that video if its actually Ed playing but on a few bits of music it sounds like a young Eddie learning his chops - possibly when Mark Stone was playing bass.

Anyone got any of this early music? Cheers
