Pretty much as described - never a star, but did a ton of stuff.
Reading up on who his brother was - responsible for producing a couple of very big acts out of England (The Who and Jimi Hendrix Experience).
Still remember seeing Superman II in the small town theater with my cousins growing up. Was a big deal back then having a movie theater in our town of 2500 showing first run movies. Sad kids today don’t know the world I grew up in down there - movie theater, arcade, record store, pizza shop selling by the slice and multiple lunch counters - no such thing as fast food.
