I saw them at Thames Polytechnic in October 1978 and they were certainly on tour around the UK during that month - I've also got an old Sounds review of a gig at Heriot-Watt University that dates from October 1978. I'm sure somewhere amongst all my other music paper 'collectibles' (or 'old rubbish' as my wife would describe them) I've got a list of dates on that tour but I can't lay my hands on it at the moment...
