Commercial bootlegers made many mistakes on their artwork. Often it was on purpose, to help disguise it as a bootleg. Sometimes it was to exploit legal loopholes (an earlier date to claim expiry of copyright, or change of location to take advantage of more liberal regimes). Often also because the bootleger was not very familiar with the material - and as time is money they are not interested in the details, only in selling the product. Fan productions I would expect to be usually pretty accurate. Looking at the copyright warning at the bottom of the last image, I guess perhaps Blue Cafe is profit driven??

> The concert in San Francisco, boarding house was held on this date 1976-06-26

No Michael in truth it was 23rd June, I have a friend who attended the gig.
Moreover Camel played an early show on this date where the encore was Lady Fantasy,
while the encore Another Night identifies the radio show as being the evening concert.
