Lees recorded a demo on a tape recorder borrowed from Olwen, and it rapidly became a live favourite, although it wasn't recorded until 1970, augmented by an orchestral arrangement by Robert Godfrey, which unfortunately would result in litigation lasting years and costing the band a small fortune.
The single was released in the UK on the Harvest label, March 3, 1971, backed by "
Vanessa Simmons". (thanks, Alexander Baron - London, England, for above 2)
