Senate Judiciary Chairman Patrick Leahy and Sen. Orrin Hatch R-Utah, got some star-studded support Tuesday for legislation they introduced earlier this month that would end a long-standing royalty exemption granted to AM and FM radio. The rally organized by the MusicFirst Coalition featured an impressive line-up of performers including: Will.i.am; Sheryl Crow; Herbie Hancock; Emmylou Harris; Patti LaBelle; Dionne Warwick and others. House Foreign Affairs Chairman Howard Berman, House Oversight and Government Reform ranking member Darrell Issa and Rep. Marsha Blackburn, R-Tenn., also attended.
