Barsotti, who along with brother Bob was a longtime Bill Graham confidante, retired after BGP was purchased by SFX Entertainment. He and his late wife, Bettike, bought the Iron Door Saloon in Groveland, Calif., in 1985. He is survived by his wife, Debra, and four children; father Mario and four brothers.

“Peter’s creative fingerprints were all over Bill Graham productions for many years – from Day On the Green sets, to backstage environments, to Bill’s New Year’s Eve “midnight rides,” decorations, special effects, logistics, you-name-it,” the Bill Graham Memorial Foundation posted to Facebook.

“Peter was one of Bill’s primary idea guys; and then Peter ushered those ideas into being. Thank you, Peter. Our hearts go out to your family and extended family.”

A memorial is in the planning stages.
