here is a similar picture with him in 'suite' and tie photographed by Lisa Coleman.

I think this performance is somewhere later Dirty Mind era - early Controversy era

this looks like it was shot in an old bathhouse on the lower wast side in nyc....gahhhhh the name escapes me now...

actually here is an ever earlier image/time of him playing keyboard 1977/78
