Corrected my also all-lower-case name at puppyflowers online.
From David Steinberg's e-mail list, got an exerpt from an SF Weekly column which gave a little history of lap dancing:
in San Francisco, the Mitchell Brothers O'Farrell Theatre was the first to offer lap dancing -- all nude lap dancing, twenty five years ago. Pulling back for the paper's audience perhaps, "The "fourth wall" of theater -- the imaginary barrier behind which an audience separates itself from the action of a play -- had been torn down. Fantasy and reality were one."
but, lap dancing was invented at "New York's Melody Theater, which pioneered the idea of strip shows with audience participation, both on- and offstage, during the 1970s"
