This original concert ticket comes from
a woman who attended the show.

Earlier this year I found a previously unknown date on the first US tour (Toledo, 29 September 1986).

Now another unknown date has been discovered:
20 August 1986: Civic Auditorium, Santa Cruz, USA

A concert at Arco Arena in Sacramento was originally scheduled for 20 August, but ended up being cancelled due to poor ticket sales. So a replacement show was held in Santa Cruz instead.

I have added the date to the 1986 – 87 tour page here.
