Sailing to Philadelphia is the second solo album by British singer-songwriter and guitarist Mark Knopfler, released on 26 September 2000 by Vertigo Records internationally, and by Warner Bros. Records in the United States. The album contains featured vocal performances by James Taylor and Van Morrison. The title track is drawn from Mason & Dixon by Thomas Pynchon, a novel about Charles Mason and Jeremiah Dixon, the two English surveyors who established the border between Pennsylvania and Maryland, Delaware, and Virginia in the 1760s. The border later became known as the Mason-Dixon Line and has been used since the 1820s to denote the border between the Southern United States and the Northern United States.
