CENSUS 2026-06-03: No recording located. Notebook/primary-source attested KSAN Live From The Plant event; no circulating tape found. The Rowan Brothers (Chris & Lorin Rowan, early-70s Bay Area, Columbia/David Grisman connection) are a plausible Record Plant KSAN act, but searches of Internet Archive/LMA, Guitars101 KSAN FM/FLAC tree, YouTube, setlist.fm and Discogs returned no Record Plant Sausalito broadcast. No confirmed date. Status: From Primary Source (notebook tier), recording unlocated. Re-crawl candidate. If found, expect FM broadcast type. Sources checked: archive.org KSAN collection, guitars101 KSAN thread. CENSUS 2026-06-03 (etree check): db.etree.org checked — no artist match for 'Rowan Brothers' in the etree live-music database; no Record Plant 1973 (or any) entry. Note: Peter Rowan (solo) has documented Record Plant *studio* demo sessions c. Aug 1973 / Apr 10 1974 with Garcia, but that is a different act and not a Rowan Brothers KSAN broadcast — not a substitute. etree adds nothing; row remains notebook-tier.
