Editing Quicksilver Messenger Service (section)

===Management===
The group's early management was by [[James Neil Hollingworth|Ambrose Hollingworth]], who became a paraplegic as a result of an automobile crash near [[Muir Beach, California]] in 1966. Hollingworth's stewardship, which also included the all-female [[The Ace of Cups|Ace of Cups]], transferred to [[Ron Polte]]. Polte was known for going to great lengths to accommodate the needs of his musicians. When perennial studio musician [[Nicky Hopkins]] joined the band in 1969, it was the first and only band that officially included him in its performing and recording revenues.<ref name=Polte>[https://www.marinij.com/2016/09/16/quicksilver-messenger-service-manager-ron-polte-dies-in-mill-valley-at-84/ Quicksilver Messenger Service manager Ron Polte dies in Mill Valley at 84] {{Webarchive|url=https://web.archive.org/web/20210218104208/https://www.marinij.com/2016/09/16/quicksilver-messenger-service-manager-ron-polte-dies-in-mill-valley-at-84/ |date=February 18, 2021 }}, ''[[Marin Independent Journal]]'', Paul Liberatore, September 16, 2016.
