Hi - not sure if this is the right place for this but...it IS tour talk.
I have a list of full tour dates for the Joel 1970s tours, with venues, and many with openers/headliners. Lots of colleges in secondary markets.
There is a site someone compiled of dates but they are missing loads of gigs especially for the 1970s. The gigs in the month of November was completely missing in their 1977 tour list I think, for instance.

I was wondering if any authors of books or researchers would be interested in utilising them?
(Not for free...not giving away the research for nothing) Perhaps someone can point me to someone who can put them to good use.
