San Francisco, also known as Iris, is an instrumental song written by Eric Avery and Dave Navarro. It was performed live a handful of times during sound checks, but never during the show itself. A few of these sound check performances were recorded and found on shows traded among fans.
The song was eventually completed for the Deconstruction album by Eric Avery, Dave Navarro and Michael Murphy. During recording of the album, it had the working title of Beverly’s Unborn. The song was eventually titled Iris, the name of Michael and Beverly Murphy’s daughter.
