William Greig (lived ca. 1812) was a Newcastle songwriter, who, according to the information given by W & T Fordyce (publishers) in “The Tyne Songster” published in 1840, has the song "A Parody Written On Hearing A Report That The Newcastle And Northumberland Yeomanry Cavalry Were To Be Disbanded" attributed to his name.
The song is sung to the tune of "The Soldiers Tear", It is not written in Geordie dialect but is definitely local to Newcastle.
The same song appears in Songs of the Bards of the Tyne, published by P. France & Co. of Newcastle in 1840. The work appears on page 161 of this book edited by Joseph Philip Robson.
