Sirius Satellite Radio [SIRI] earlier this week launched Elvis Radio, a 24-hours-a-day radio station dedicated to the music of Elvis Presley. Sirius officials said the music would cover his entire career, including the hits, the “b” sides, and rare tracks and concerts. The company said a special studio has been set up at Graceland, Presley’s Memphis, Tenn., home, from which Sirius DJs will broadcast.
