It is not believable that Congress intended to provide by this amendment that every member of a religious congregation joining publicly in the singing of a copyrighted tune should be liable to the penalties prescribed by this section; nor even that every member of a church choir, having purchased the copies of the copyrighted anthem, sold only for such purpose and useful only for such use, should be subject to these penalties, if the publisher omitted to grant expressly the permission to sing with the sale of a printed copy. But no other interpretation can possibly be derived from the present section unless the word "perform" is taken as applying to dramatic performance and as not including mere vocalization in public. The present bill is intended to leave no doubt upon this point, and in that respect it is contrary to public policy, sound sense, and every consideration of justice. The holder of a musical copyright should not be vested, by virtue of that copyright, with the right to sell his music, which is made to be sung, and prohibit its singing; to sell his music, which is made to be played, and prohibit its playing. Still more obnoxious to justice is it that one who has been openly sold a copy of a piece of music, and who has done with it that which constitutes the only motive for buying it, namely, has sung it, or played it, or procured some one else to sing it for his entertainment, should, if he chances to do that in public, be penalized and put in the position of one who has committed a misdemeanor or transgressed another's rights. Reason and sense revolt at such a statute or such an interpretation of a statute; and musical composers demanding such rights place themselves in contempt of civilized society. Section 4966 should be amended by making clear that it relates only to dramatic performance, while it includes such performance of compositions which are musical as well as dramatic. And all provisions of the present bill exceeding such protection should be limited.
