@larsman -- Larry, you have some freaking fantastic photos. Some that stood out: the Robin Trower "faces" shots; Phil looking menacing in Thin Lizzy; "Flower" and "Watcher" Gabriel; and of course, David Gilmour.
I've heard a bootleg recording of that Montrose show at Winterland -- incredible. I saw Montrose right before Hagar left. Such a shame...they could have been a force for a long time. Again, great work. I'll be in touch.
