The second session took place at Wessex studios in Highbury, North London in October 1976 that resulted in an early take of 'Anarchy in the UK' the third and final session took place at Gooseberry studios in Soho in January, 1977. It was during these final demo sessions where the band recorded the first takes of 'God Save the Queen', 'Problems', 'Pretty Vacant', 'Liar', 'Who Was it (EMI)' and 'New York (Looking for a Kiss).
