Da Hollywood-famous "Catherine B" once had a major
wardrobe-malfunction on set, and so if said "whoopsie in da modesty department" event had happened in front of da great "Johann B", even he --- while indeed being infamous for boldly "
breaking new ground" as far as musical styles went, was still very
conservative and proper in his general "beliefs 'n' behavior" --- might have been so shocked and nonplussed dat it would have interfered with his being able to correctly compose/perform his music at da time, and thus said situation might have resulted in a major "double debachle".
