Terrific actor and again, when any Columbo alumni passes, the first thing I think of is their role(s) in any Columbos they've been involved in not their extensive careers!
Even though I don't really know "Rock Star," and even though Murray in "Double Shock" isn't one, nobody could play a comical con artist better than he could, even playing them in a few entire series of his own.
When it comes to things connected with COLUMBO, he pla*** a character framed for murder by Gene Barry in the Levinson and Link ALFRED HITCH**** HOUR episode "Dear Uncle George."
