Don't forget that part of Prince's "Purple Rain" was filmed just outside of Henderson.
I don't have any videos of Henderson but I have some cassette tapes of a 1980's school play, 1982 graduation ceremony (with Gov. Al Quie as speaker) and a very funny tape that was made on our '82 senior class trip.
(Skeddy, I almost hope there is no bus footage. You are painting a pretty scary picture!)
