Gypsies, Tramps and Thieves was first recorded in 1971 by Cher and was her first #1 hit as a solo artist. It was written by Bob Stone as a story-song originally titled "Gypsies and White Trash" until producer Snuff Garrett asked Shel Silverstein to re-work it.
Dervish is a traditional Irish music band formed in 1989 and based in County Sligo. They chose the name Dervish as it relates to any group of spiritual people who become enraptured by music.
