Notes from San Francisco: Notes from San Francisco is a posthumous album by Irish musician Rory Gallagher.  Released in 2011, It consists of two CDs.  The first disc is a never released album that Gallagher recorded in San Francisco in December 1977.  The album was to be a major shift for Gallagher.  Rather than producing it himself he worked with Elliot Mazer a successful producer who had a long track record with artists such as Bob Dylan, Janis Joplin, and The Band.  At the last minute -- causing great distress to his manager and brother Donal and to his record company -- Gallagher decided to just pull the record.  In an interview Gallagher stated "it wasn't because of the material or the musicians or anything like that.  It was a song thing that I didn't think on the technical side everything worked.  So I scrapped the thing" After scrapping the album Gallagher reworked his band firing all the musicians except the bass player and hiring a new drummer.  This new Gallagher power trio re-recorded the San Francisco songs with Gallagher producing and released them as Photo-Finish.  Shortly before his death, Rory reportedly gave Donal permission to eventually release the original San Francisco versions of the songs if they were remixed.  Donal had his son Daniel remix the songs in 2011.  The second disc is a live performance also recorded in San Francisco in December 1979.

Sierra Nevada (ferry): Sierra Nevada was a steel-hulled steam-powered passenger ferry operated on San Francisco Bay.  The ferry was built for the Western Pacific Railroad as "Edward T. Jeffery" in 1913 and subsequently renamed "Feather River".  The ferry offered connecting service to San Francisco for Western Pacific train passengers arriving in Oakland, California.  The ferry was sold to Southern Pacific Transportation Company when Western Pacific began using Southern Pacific's Oakland ferry facilities in May, 1933.  Southern Pacific renamed the ferry "Sierra Nevada" and placed it in commuter service between San Francisco and Alameda, California until that route was discontinued in 1939.  The ferry was leased to the Key System for the Golden Gate International Exposition on Treasure Island from 1939 through 1940.  In 1942, the ferry was requisitioned by the federal government to carry shipyard workers from San Francisco to Richmond Yard 1 through World War II.  The Richmond-San Rafael Ferry Company purchased the ferry in 1947 and rebuilt it to carry automobiles between Richmond and San Rafael until the Richmond–San Rafael Bridge opened on 1 September 1956.  The ferry was then towed to San Pedro, Los Angeles where she sank in 1978.
