The New York Times reports that Local 802 of the American Federation of Musicians has filed unfair labor practice charges against the new producers of "Tony & Tina's Wedding" who want to change from live to recorded music.  The producers are alledged to have locked out the musicians and denied them access to their musical instruments.  In 2008 the AFM entered into a new collective bargaining agreement with the former producers of the show to run through May 2011.  That agreement is asserted by the AFM to bind the new producers.
