It's TRUE! I was at Graceland this past weekend (will post some pics on Siriusbackstage.com today/tonight...), and it was really great to see this "Elvis/Sirius exposure here".
Graceland is the second most visited house in the United States, behind the White House; it's been stated that over 29 million Americans have visited Graceland; so, no telling how many people total, from all over the world!
Sirius just keeps amazing me over their added content; truly amazing, and they don't stop, they just keep getting better and better!
