4 Mar 1966 "Substitute" backed with "Circles" is released in the U.K. To get around a planned injunction brought by their former producer Shel Talmy, the single also comes with a new label affixed to the b-side, re-titling the song "Instant Party". https://t.co/CmMgyGlhgk pic.twitter.com/mwYCBeV6Du
