I did a superficial search and didn't find anyone with a Santana or Journey connection who seemed to match. Gregg Rollie today has the blond hair thing going but doesn't look like the guy in the photo. I'd go with DLR until we get more info
Huh. I think you are right! I thought the photo looked like a very early Schon, pre-Journey, which would be too early for DLR to be there. But it's not!
