Wouldn't have a clue -
each venue has different seating capacity and they charge different rates...perhaps some places don't charge..I don't know..
and then there's the plane rental/pilot fees/dollar exchange/truck transport/driver,hotels/meals etc. when he's touring the u.s. (which he does much more frequently than Canadian tours)
I wouldn't know how much any of those expenses would be....
and he doesn't offset any of those expenses with a retail sales table of "Lightfoot" products...
but I think I can be safe saying can be safe in saying that it's worth his time to tour...
