It says that this was researched by the guys at PW. And I LOVE that tourography at the PW site. But isn't that still a bit incomplete?
Last I checked, there were some questions about the "Down the Tobes" tour. I'm pretty sure they confirmed that there was definitely a headlining show on that tour....and it would seem reasonable that they may have played the full Fountain of Lamneth at such a show, but apparently not even the band themselves can confirm that. Again...the last time I looked into it.
1/10/76 (Not bootlegged as was the rumor)
Supposedly the band was involved with confirming the tour dates and they did retroactively put tour dates on the back of the replica tour shirts when they reissued them some years ago, but who knows if they are correct.
Band officials haven't been accurate with some of the album release dates, one being 2112 which was released in mid-March, not April 1, 1976 which kind of has become the celebrated date.
I keep meaning to do some research myself on this (album release dates) but haven't gotten around to that yet.
It's possible this new book gets some of its information from the Rush Chronology Book which is a listing of events in Rush history by date, but I'm not sure if that is totally accurate either.
