gerry and the pacemakers

[missyabrahams]

I am going back a long time but maybe someone can help. I am trying to get the date that Gerry & the Pacemakers played in Auckland in 1964. it was in April sometime the concert was called the Liverpool sound show featuring Gerry & the Pacemakers, Gene Pitney, Dusty Springfield and Brian Poole & the Tremeloes. any help I can get would be much appreciated. I cannot find anything on the net. To show my age I was there but the date escapes me.
Thank you All
