Thanks for that Snowdog. That is just one of many references that I came up with also. Normally something like this wouldn't bother me too much but I really need to find out, a ticket stub or something would do the trick. There are just too many discrepencies.
I know that Rush were headliners for that concert with Status Quo during the FBN tour, and I know it was at the Michigan Palace because my hometown is Windsor and I know the Detroit area very good. Could it be that this gig is not documented anywhere? I know it is not documented on any Status Quo site and there are quite a few websites.
Maybe that Quo gig in Grand Rapids I mentioned above is off by 1 day, (but it is documented for April 13 '75). If so then I would venture to guess that Rush were last minute headliner replacements for Kiss, who were booked in Missouri that evening.
I just can't let this one die.
