"Itchycoo Park" is a song written by Steve Marriott and Ronnie Lane, first recorded by their group, the Small Faces. Largely written by Lane, it was one of the first music recordings to feature flanging, an effect at that time made possible by electro-mechanical processes. The location and etymology of the titular park has long been debated; many claiming it to be Little Ilford Park in Manor Park, East London, Valentine's Park in Ilford or Wanstead Flats in Wanstead, East London. The single was not featured on any of their UK albums, but was however featured on the North American release There Are But Four Small Faces.
