This source was mentioned in the "SF to Sydney" thread, but I don't think it has been listed here so I will add it. John Mason's BEFORE THE MAST IN SAILING SHIPS recounts his experience on a cruise in 1884, from Newcastle in New South Wales (Australia) to San Francisco, with a cargo of coal. At one point he mentions and quotes from three chanties: "The Banks of the Sacramento", "Santy Anna", and "Sally Brown". The songs are being sund by "Campbell's men" as they load wheat at Port Costa.

Later on, in Liverpool (I think), they hove up the anchor and made "the Mersey ring", singing "Leave her, Johnny, Leave her," and "Sally Brown". Mason gives us quotes from those two songs.
