How do I know this?
I took a “street level tour” of the Rose Garden and on the sign at the North End of the Rose Garden, an event on “the 23rd” is referred to. I then journeyed to the Aladdin Theater nearby and read the marquis…the first artist mentioned was “Jesse Winchester” who was playing “on the 23rd”. A little bit of research confirmed that Jesse played Portland on 8/23.
That is how I know.
