Filmmakers working on a documentary on bar and bat mitzvahs are looking for videotape submissions. The project grew out of �Bar Mitzvah Disco,� a book cataloging bar mitzvah pictures, stories and memorabilia from the 1970s, 1980s and 1990s. The spinoff film � titled �Bar Mitzvah Disco: The Video� � is supported by American Apparel, an L.A.-based clothing store and manufacturer. Video submissions can feature any hallmark of the American bar mitzvah � from candle-lighting ceremonies to renditions of the song �YMCA� � and will be returned after use.
