WASHINGTON (AP) - Roger McGuinn of The Byrds, Richie Furay of Buffalo Springfield, Sam Moore of Sam and Dave and Martha Reeves are among the acts who are part of an effort supporting a proposed law to pay better royalties to artists. They're part of the Project72 campaign that supports the Respect Act, a proposal to require digital radio services to pay artists who recorded before 1972. They say digital music services interpret state and federal law in a way that allows them to use pre-1972 songs without paying for them. Gene Chandler says he's seen oldies acts who need the money perform sitting on stools or in wheelchairs. Otis Redding's daughter, Carla, says her father's estate has seen a 90 percent drop in income because digital services won't pay. Other acts supporting the campaign include The Allman Brothers Band, The Beach Boys, Melissa Etheridge, Al Green, B.B. King, The Moody Blues, Cyndi Lauper, and Three Dog Night.
