from James M.
The show was scheduled for 12 September 1979 but John McKay the guitarist and Kenny Morris the drummer of Siouxsue walked out.
The show was rearranged for 24 September with Robert standing in on guitar and Budgie on drums.
I think the 12 September show was sold out and we all used our 12th tickets on 24th so you are not likely to see a ticket for 24th.
