"I Live In Trafalgar Square" was written by C.W. Murphy. Copyrighted 1902 by Francis, Day & Hunter; it was first sung by Morny Cash, and has been described as patriotism turned to irony and cynicism. The meaning of the song will be lost on those unfamiliar with British history or the topography of the capital. Although London's Trafalgar Square is well known as the haunt of pigeons, its most famous resident is Lord Nelson.
Horatio Nelson was Vice-Admiral of the British Fleet; his finest victory was the Battle of Trafalgar in 1805, in which he was mortally wounded. Trafalgar Square was constructed to commemorate the Battle, and Lord Nelson "lives" on top of Nelson's Column, which was completed in 1843, where he is guarded by the four lions who feature in the Mark Knopfler composition
which was recorded by Dire Straits. See it in Song Images
