Just heard he died a couple of days ago. Mainly will be remembered as one of the Yardbirds as guitarist and then bass player. I always thought of him as the quiet one. He got involved in potography for a while too. Got involved with a later version of the Yardbirds but had to quit about 12 years ago for health reasons. Apparently, Jimmy Page offered him membership of his new band as bass player back in the day.
