Notwithstanding any provision of the general statutes or any special act or any municipal charter to the contrary, a municipality or a civic center authority or a coliseum authority created by a municipality may be the backer of a coliseum permit or coliseum concession permit, or both, provided approval is given therefor by the legislative body of such municipality. Governmental immunity shall not be a defense to any cause of action arising out of operation under such permit.
